JTable user resize columns with grid?

Is it possible to allow a user to resize columns not just through the table header, but with the vertical grid lines?

There is no method that allows you to toggle this
feature on/off if thats what you are asking.Yes, thats what I was asking.
If you want to implement this type of functionality
yourself then take a look at the source code for
JTableHeader to see how its done.Thanks, I'll look into that - though it would be cool if that was already a feature of JTable.

JTable: Easy groupable column headers with hideable columns

Hi All,
I have a requirement to make a JTable which displays
columns with 2 values - a current value and an old one.
The old value can be hidden or shown by user preference.
The values are not editable. The 2 values have a single
heading.
I've been mucking about with GroupableTableHeader and
HideableTableColumnModel and all that. This way of
solving the problem requires siginificant coding.
Then I had an idea - just use the TableCellRenderer to
make it look like 2 columns ! This fits my requirements
and is much simpler.
So for anyone who has the same requirement, here is
some sample code. I think you'll all agree that in my
specific case it is a very good way of providing the needed
functionality.
Here is the sample code:
import javax.swing.*;
import javax.swing.border.AbstractBorder;
import javax.swing.table.AbstractTableModel;
import javax.swing.table.DefaultTableCellRenderer;
import java.awt.*;
import java.awt.event.ActionEvent;
public class DoubleColumnTable extends JTable {
    private boolean secondValueVisible = true;
    public DoubleColumnTable() {
        super();
        setModel(new AbstractTableModel() {
            public String getColumnName(int column) {
                return column + "";
            public int getColumnCount() {
                return 5;
            public int getRowCount() {
                return 5;
            public Object getValueAt(int rowIndex, int columnIndex) {
                return new Integer[]{new Integer(rowIndex), new Integer(columnIndex + 10)};
        setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                Integer[] twoValues = (Integer[])value;
                JPanel panel = new JPanel();
                if (secondValueVisible) {
                    panel.setLayout(new GridLayout(0, 2));
                    JLabel firstLabel = new JLabel(twoValues[0].toString(), JLabel.CENTER);
                    JLabel secondLabel = new JLabel(twoValues[1].toString(), JLabel.CENTER);
                    secondLabel.setBackground(Color.lightGray);
                    secondLabel.setOpaque(true);
                    secondLabel.setBorder(new LeftBorder());
                    panel.add(firstLabel);
                    panel.add(secondLabel);
                } else {
                    panel.setLayout(new GridLayout(0, 1));
                    JLabel firstLabel = new JLabel(twoValues[0].toString(), JLabel.CENTER);
                    panel.add(firstLabel);
                return panel;
    private void toggle() {
        secondValueVisible = !secondValueVisible;
        repaint();
    class LeftBorder extends AbstractBorder {
        public void paintBorder(Component c, Graphics g, int x, int y, int width, int height) {
            g.setColor(Color.gray);
            g.drawLine(x, y, x, height);
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setSize(300, 300);
        frame.setLocation(300, 200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container contentPane = frame.getContentPane();
        final DoubleColumnTable table = new DoubleColumnTable();
        contentPane.add("North", new JButton(new AbstractAction("Toggle") {
            public void actionPerformed(ActionEvent e) {
                table.toggle();
        contentPane.add("Center", new JScrollPane(table));
        frame.setVisible(true);

This should read
"I have a table with column headers and a row headers using a single column from a second table."

Can i set only 1 column in a jtable to resize?

Hi,
I want to set only the columns with "Strings" as content to be resizable inside my jtable. and leave those which are ints, as a fixed size, but I haven't been able to find a way of setting the resizing options for a specific column...
any ideas?

You would need to check the column number and the data type in the column being resized and force it back to a set value if it was not a column with a string in it. Remember the user can swap the columns.

For all users having probs with OO ALV Grid

I wanted to put this in the WIKI but it keeps bombing out when I try and save so I've put this here -- Maybe a MOD can move it for me.
This generic class should give you far more insite into using an EDITABLE ALV table than the standard documentation.
If you follow the steps you should be able to code very quickly a decent useable ALV OO program which can retrieve and manipulate data very easily. The events are (hopefully) well documented as are all the steps.
Once you understand the basics you can add more functionality like colouring Cells, adding hyperlinks etc etc.
I've always found that stupid SEAT / AIRLINE application SAP uses for its examples far too overblown and in reality who would ever use a SAP system for Airline reservations anyway.
The class here describes a much simpler application which CLEARLY (I hope) explains how the whole thing works.
Jimbo's generic class for using the OO ALV GRID Class CL_GUI_ALV_GRID
from an application program to display and manipulate ANY table
with minimal coding needed in the Calling application program.
Handles the following EVENTS
1) TOOLBAR BUTTONS
(you can add more to the toolbar method
if you need even more functionality).
2) DOUBLE CLICK
3) ENTER KEY PRESSED
4) DATA CHANGED
5) DATA CHANGED FINISHED
Methods available
PUBLIC METHODS ( Can be called directly from the application program).
1) display_grid displays grid with toolbar
   Table and FCAT are built dynamically - user only needs to
   define the table structure (can be DDIC or User fields)
2) change_title - changes title at the top of the Grid
3) refresh_grid   - refreshes grid after table updated etc.
4) build_dynamic_structures - this method creates a dynamic table and a dynamic FCAT
   using the structure defined in the calling application program
PRIVATE METHODS (Internal Methods used within the class)
1) verwerk - returns to FORM VERWERK in calling application program
   (Via Toolbar). The application program can then do any special processing
   at this point e.g update SAP tables etc.
2) download_to_excel (via Toolbar). This creates an EXCEL spreadsheet
   directly which can be downloaded / saved to a file if required,
3) return_structure - internal method returns the structure
   of the table defined in the calling application program. This is needed in order
   to build the dynamic table and Field Catalog.
4) create_dynamic_table - creates a dynamic table from the structure defined in
   the calling application program
5) create_dynamic_fcat - creates the dynamic field catalog from the structure
   defined in the application program.
6) dubbleklik entered when user double clicks a cell
activated by EVENT DOUBLE_CLICK.
returns to FORM DUBBELKLIK in the
calling application program
   COOKBOOK STEP BY STEP instructions on how to use this class
   in your application program.
   In the application program :
1) define a blank screen 100 - SE51 with a custom container
   on it called CCONTAINER1.
   you need the following logic in the screen
   The PAI is only used if you have defined a STATUS with SE41 and you exit the
   application program via the standard SAP buttons on the
   top of the Screen (NOT the GRID toolbar).
     PROCESS BEFORE OUTPUT.
      MODULE STATUS_0100.
     PROCESS AFTER INPUT.
     MODULE USER_COMMAND_0100.
2) (optional) define a STATUS with a titlebar - SE41
   you only need this if you want the standard EXIT and menu buttons on the
   top line of the screen
3) If you want to have your OWN colum names on the grid
   add the following macro to the start of your program
     DEFINE col_name.
     read table it_fldcat into wa_it_fldcat index &1.
     wa_it_fldcat-coltext = &2.
     modify it_fldcat from wa_it_fldcat index &1.
     END-OF-DEFINITION.
4) Define the following Field symbols
   <fs1>           TYPE ANY,
   <fs2>           TYPE STANDARD TABLE,
   <fs3>           TYPE ANY,
   <field_catalog> TYPE STANDARD TABLE,
   <dyn_table>    TYPE STANDARD TABLE,
   <orig_table>   TYPE STANDARD TABLE,
   <dyn_field>,
   <dyn_wa>.
5) After the field-symbols add the code in this class
    as an INCLUDE
    e.g INCLUDE ZZJIMBOXX_INCL.
6) define your Internal table as follows
    TYPES: BEGIN OF s_elements,
              Your structure
            your structure etc.
            END OF s_elements.
For example
INCLUDE <icon>.
TABLES: VAPMA.
*TYPES: BEGIN OF s_elements,
vbeln   TYPE vapma-vbeln,
posnr   TYPE vapma-posnr,
matnr   TYPE vapma-matnr,
kunnr   TYPE vapma-kunnr,
werks   TYPE vapma-werks,
vkorg   TYPE vapma-vkorg,
vkbur   TYPE vapma-vkbur,
status TYPE c,
*END OF s_elements.
7) Define the following data IN YOUR APPLICATION PROGRAM
   (note here only data is described
   that relates to using THIS CLASS. Data purely used internally
   in the application program is NOT shown here).
DATA: z_object          TYPE REF TO zcl_dog, "Instantiate our class
      grid_container1    TYPE REF TO cl_gui_custom_container,
      t_elements         TYPE TABLE OF s_elements, "refers to our ITAB
      wa_elements        TYPE s_elements,
      wa_dyn_table_line TYPE REF TO DATA,
      it_fldcat          TYPE lvc_t_fcat,
      i_gridtitle        TYPE lvc_title,
      wa_it_fldcat       TYPE lvc_s_fcat,
      new_table          TYPE REF TO DATA,
      dy_table           TYPE REF TO data,
      dy_line            TYPE REF TO data,
      row_id             TYPE sy-index.
8) insert the following code at the start of the application program.
*START-OF-SELECTION.
*CALL SCREEN 100.
*END-OF-SELECTION.
*MODULE status_0100 OUTPUT.
*ASSIGN wa_elements TO <fs1>.
*CREATE OBJECT z_object EXPORTING z_object = z_object. "Instantiate the class
*CALL METHOD z_object->build_dynamic_structures
       CHANGING it_fldcat = it_fldcat.
9) if you inserted the macro in step 3) then
   define your own column names as follws
col_name 1 'Name1'.
col_name 2 'Name2'.
etc. The number is the colum number you want and the name is
the name you want to assign to the column.
for example using the table shown above
col_name 1 'Order Nr'.
col_name 2 'Item'.
col_name 3 'Material'.
col_name 4 'Customer'.
col_name 5 'Plant'.
col_name 6 'Sales Org'.
col_name 7 'Sales Office'.
col_name 8 'Status'.
10) perform a routine that fills your dynamic table and
     display the GRID. If you created a status with SE41 you can set
     a title etc. Further processing is dependent on the users action
     after the GRID is displayed for example if a Cell is double clicked,
     dat is entered, a toolbar button is pressed or a SAP ICON on top of the screen is pressed.
PERFORM populate_dynamic_itab.
CALL METHOD z_object->display_grid
      CHANGING it_fldcat = it_fldcat.
SET PF-STATUS '0001'.
SET TITLEBAR '000'.
ENDMODULE.
11) If you added a STATUS via SE41 you can exit the program via the
standard SAP buttons at the top of the screen
otherwise exit via the exit button on the toolbar.
You only need this piece of code if you defined a STATUS in the application program
MODULE user_command_0100 INPUT.
CASE sy-ucomm.
   WHEN 'BACK'.
     LEAVE PROGRAM.
   WHEN 'EXIT'.
     LEAVE PROGRAM.
   WHEN 'RETURN'.
     LEAVE PROGRAM.
   WHEN OTHERS.
ENDCASE.
12) to populate the dynamic table you only need to code something like this
remember the class has already created and structured the field-symbol <dyn_table>
so you don't have to do anything other than just select the fields you want
filled and from what data source(es).
*FORM populate_dynamic_itab.
*SELECT vbeln posnr matnr kunnr werks vkorg vkbur
      UP TO 200 rows
      FROM vapma
      INTO CORRESPONDING FIELDS OF TABLE <dyn_table>.
if you want to keep the original table before making any changes etc code
the following
create 2nd Dyn table to hold original data. We can use
the same field catalog as for the original table
as we are just creating an identical copy here.
*CALL METHOD cl_alv_table_create=>create_dynamic_table
   EXPORTING
        it_fieldcatalog = it_fldcat
     IMPORTING
        ep_table = dy_table.
ASSIGN dy_table->* TO <orig_table>.
CREATE DATA dy_line LIKE LINE OF <orig_table>.
ASSIGN dy_line->* TO <dyn_wa>.
<orig_table> = <dyn_table>.
ENDFORM.
13) you need these 2 processing routines in your application program.
FORM VERWERK. "Entered from VERW on toolbar
*break-point 1.
Orig table is in dynamic table <orig_table>
ALV GRID changed table is in <dyn_table>.
*Loop at <orig_table> into <dyn_wa>.
Do what you want here
end
endloop.
ENDFORM.
*form dubbleklik using     "Entered when a cell is double clicked
       e_row   type LVC_S_ROW
       e_column type LVC_S_col
       es_row_no type lvc_s_roid.
       break-point 1.
Get Row id into a variable for this program.
       row_id = e_row.
        SET TITLEBAR '001'.      "If you defined a status in SE41
       i_gridtitle = 'Grid Title Changed'.
       CALL METHOD z_object->change_title
         EXPORTING i_gridtitle = i_gridtitle.
       PERFORM refresh.
endform.
The REFRESH routine is optional but after a double click I assume
you want to do some processing
and re-display the data
so as a sample code something like
*FORM refresh.
data: ord_nr TYPE vapma-vbeln. "Your data
*READ TABLE <dyn_table> index row_id into wa_elements.
   ord_nr = wa_elements-vbeln.
You've now got the Row double clicked so pick out the data element(s)
you wnat to process and do your processing
*set parameter id 'AUN' field ord_nr.
*CALL TRANSACTION 'VA02' AND SKIP FIRST SCREEN.
You can update the dynamic table for example
*wa_elements-status = 'C'.
*modify <dyn_table> from wa_elements index row_id.
now redisplay the updated grid.
*CALL METHOD z_object->refresh_grid.
*ENDFORM.

Hi Dinu,
Before analysing ALV, please cross check the behaviour of the calling program.
Is the control really going to the application server when you do all the above process?
If so, when user makes some changes are they saved in the data base / affected the internal table which you are using for ALV?

Surya.

Resizing columns in a JTable in a JScrollpane

I have a JTable in a JScrollpane and I after I load the table, I resize the columns to fit the data (works well).
The problem is that I want the scrollpane to stay the same size and let the table scroll horizontally inside the viewport. The actual result is the scrollpane stretches to the width of the table causing the user to scroll the panel rather than the scrollpane.
I've tried setting the scrollbar policy but that didn't work.

I am passing the JTable to the constructor of the JScrollPane.
I have a JTable in a JScrollPane that sits on a JPanel which is in a JScrollPane itself.
After I load the data into the JTable, I resize all of the columns to fit the data.
The problem is that the JTable resizes wider than original size causing the whole panel to scroll horizontally. I would rather have the JScrollPane that the JTable is in scroll.

Set multi user column with PowerShell used to work in 2010 but no longer works in 2013

In SharePoint 2010 I used PowerShell to set the value of multi user people columns and it worked really well. I attempt to use the same PowerShell to set the same column type in SharePoint 2013 and it fails.
here is the PowerShell that I use in 2010:
$web = Get-SPWeb "http://intranet"
$list = $web.lists["TestList"]
$item = $list.items.add()
$item["Title"] = "Test multi user column"
$users = @("Domain\user1", "Domain\user2")
$userList = new-object Microsoft.SharePoint.SPFieldUserValueCollection
foreach($user in $users)
$spUser = $web.EnsureUser($user)
$userValue = new-object Microsoft.SharePoint.SPFieldUserValue($web, $spUser.ID, $spUser.Name)
$userList.Add($userValue)
$item["MultiUserColumn"] = $userList
$item.update()
I have used this on three SharePoint 2013 farms with differing results. On two of them I receive an error when running $item.update(): Exception calling "Update" with "0" argument(s): "Invalid look-up value. A look-up
field contains invalid data. Please check the value and try again."
If I take one of the users out of the $users list then it works fine, but it will not allow multiple users to be set with PowerShell. I can use the GUI to add more than one user but not PowerShell.
Does anyone know if these methods have changed in 2013? I haven't been able to find anyone else with this issue.
mmm... coffee...

Not sure but maybe something to do with casting. Below is the code snippet from one of the blogs. Try modifying your script like below and see if still you get the error
[Microsoft.SharePoint.SPFieldUserValueCollection]$lotsofpeople = New-Object Microsoft.SharePoint.SPFieldUserValueCollection
$user1 = $w.EnsureUser("domain\user1");
$user1Value = New-Object Microsoft.SharePoint.SPFieldUserValue($w, $user1.Id, $user1.LoginName)
$user2 = $w.EnsureUser("domain\user2");
$user2Value = New-Object Microsoft.SharePoint.SPFieldUserValue($w, $user2.Id, $user2.LoginName);
$lotsofpeople.Add($user1Value);
$lotsofpeople.Add($user2Value);
$i["lotsofpeoplefield"] = $lotsofpeople;
$i.Update();
#-or-
$l.Fields["lotsofpeoplefield"].ParseAndSetValue($i,$lotsofpeople);
$i.Update();

Add column with preq number to ALV grid in me53n

hi all,
i am trying to add column with preq number (BANFN) to ALV with preq items in ME53N. it is not available in column set, when trying to add by "change layout" button - i dont understand why, when the strcucture MEREQ3211GRID contains it :-(
i also tried to add new field ZZBANFN into the structure CI_EBANMEM and after that, i could add the new field to ALV through change layout, but it was empty of course. so i implemented EXIT_SAPLMEREQ_001 from MEREQ001, but ZZBANFN is still empty, because this exit is not called when opening ME53N, but when clicking on tab "customer data" in preq item detail.
how to solve this? is there any exit that is called before displaying the ALV grid?

Here is some more detail. I included my code from the Enhancement.
ENHANCEMENT-POINT MM06EFPO_POT_AUFBAUEN_02 SPOTS ES_MM06EFPO_POT_AUFBAUEN INCLUDE BOUND.
   ENHANCEMENT 1 Z_MM06EFPO_POT_AUFBAUEN_1.    "active version
SELECT SINGLE zz_old_material FROM mara
    INTO pot-zz_old_material
    WHERE matnr = pot-matnr.
ENDENHANCEMENT.
You will also need to change the layout in Item Overview to bring your field in.

Resize column width for JTable without column headers?

Hi,
I find that for me to resize columns of a JTable by using
mouse dragging, I MUST have column headers and then drag
column headers to resize them. Is my understanding correct?
Actually, I need to have a table without header columns.
How can I use mouse to resize column width by dragging?
The background for this request is that I am putting a
complex table as another table's column header and I hope to
be able to resizing the complex table by mouse dragging.
Thanks very much,
David

Hi,
I think you have mistake there. Try
<style type="text/css">
table.apexir_WORKSHEET_DATA td {
white-space:nowrap !important;
td[headers="DESCR"] {
width:300px !important;
max-width:300px !important;
#apexir_DESCR {
width:10px;
max-width:300px !important;
</style>And you can try add
table.apexir_WORKSHEET_DATA {
width: 100% !important;
table-layout: fixed !important;
}Regards,
Jari

Updates to JTables and resizing of columns

I'm building an application that has many tables that all use table models that I have created. All of the table models extend DefaultTableModel. Before entering any data in the tables i set the size of the columns. Below is an example of how I do this...
      //tcm = table column model
      tcm.getColumn(0).setPreferredWidth(100);
      tcm.getColumn(1).setPreferredWidth(100);
      tcm.getColumn(2).setPreferredWidth(100);
      tcm.getColumn(3).setPreferredWidth(100);
      tcm.getColumn(4).setPreferredWidth(172);
      tcm.getColumn(5).setPreferredWidth(172);
      My problem is everytime I update the table with new data the columns keep adjusting themselves to the width of the largest piece of data in the particular column. In order to keep the size of the columns I want I've been resizing the columns with the above code everytime I update the table. Can someone tell me how to set the column sizes once and have them remain that way?

JTable width resize

Hello,
I insert a JTable without header in a JTextPane. I'm able to resize the width of the columns with the mouse, but the JTable isn't resized. I call the method JTable.setWidth(int width); to set the start width.
Do anyone knows a solution ?
Thanks in advance

Usually a JTable is added in an JScrollPane. Please use setMinimumSize() or setPreferredSize() to set this pane the size you want it to start.

User input in ALV Grid

Hello All,
Is it possible to have a user input in ALV grid. I know there can be editable columns/cells but suppose the application demands an input field to be placed in ALV Grid where the user will enter some value.
Could someone please suggest if this can be done.
Regards
Indrajit

Here's THE definitive way to do it.
This little proggy demonstrates the following.
1) Create a DYNAMIC FCAT for an internal table with USER defined fields (i.e non ddic) and colour some columns in the FCAT.
2) Create a DYNAMIC TABLE.
3) Define a subclass of CL_GUI_ALV_GRID so you can access some very useful protected methods and attributes - you can get original and changed table IN ROWS which is a lot easier sometimes than messing around with individual
cells.
4) Create extra buttons on the toolbar.
5) Define EVENT handlers including data change so you can get control when the user enters data. YOU DON'T NEED PAI anymore with event handlers.
6) Call methods in your subclass of CL_GUI_ALV_GRID (you can also call methods in CL_GUI_ALV_GRID by virtue of Inheritance) from methods in your event handler class.
7) Display an editable Grid.
This method will work for almost any conditions you need to use.
I'm sure this covers all the bases -- please reply if any queries.
Run the program, click on the EDIT button and enter your data. Press ENTER when done.
All you need to do is copy this code and create one empty screen (SE51) with a custom container called CCONTAINER1 with the following logic in it.
PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0100.
(In the program you don't actually do anything in the PAI as the event handler takes care of this)
Now here's the program
PROGRAM zdynfieldcat.
class zcltest definition deferred. "For field symbol reference.

ORA-01400 - not null column with default value and item with authorization

I've searched - I would think someone has run into this. APEX 3.0.0.00.20 - I've created a simple form on a table. One of the column is a not null column with a default value. I have a select list on that item, but it has security on it - authorization scheme. So, it checks the user and if that user isn't of the right role, it will not even display that item. However, APEX appears to still send in the column in its sql! So, the default value is useless, it sends in null each time. Even if I set the default at the Item level, I get null. Argg. That's got to be a bug...
In debug, I do not see the item listed at all. It's not used. That's fine - but why is it trying to insert the value? I would think it would leave it off??? I think because the item is associated with a database column. But, getting around this is ugly. Having to create a hidden item for each one, and then check to see if I need to take the list value... horrible. Any way to get around this???

I should add - I guess I can always put my own custom process in to replace the DML. Just seems like a simple thing - if the value doesn't appear on the debug, isn't set with any default value... don't include it in the DML.

How to order an entire Report by a column with in a group...

Okay, I have a Group Above report, and I want to order the groupings by a column within the group. I am using a lexical parameter in place of the entire ORDER BY statement in the query, giving the user the capability to sort the report by any specific column, at runtime.
So, basically, this parameter allows for the ORDER BY to be dynamic; however, in the Data Model, I am required to designate at least one hard-coded break column, which overrides whatever column is designated by the user at runtime.
Any ideas how I can get around this?

Hi Brice,
If you want just i single hard coded column in a group
then i think you can create summary column with counting
so you can say say a column that gives you just Serial no.
and rest of the thing as it is.
in this way you got your hard column and also Order by facility
that you want.
Hope that helps you.
Enjoy Oracle....
