Hi,
we are working on it
In the meantime you could undeploy all versions you had deployed and take this version:
[table_final.zip|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f06c0940-79ca-2910-14b5-c4de1efd3bf5], which you also can find here: [WEb Dynpro Samples and Tutorials: Creating Tables|/docs/DOC-8061#46].
I tried it myself and after a repair it did run without problems.
kind regards

Spry for sorting tables tutorial

I have a static table with 5 columns 10 rows and would like the user to be able to click anyone of the columns to get accending order or deccending order, to see how they rank as per column headings. I have looked at many javascript scripts, but did not work well or not what I wanted, so I thought why not spry. I looked at the spry samples on adobe site but there was no tutorials to go along with the sort table sample. If any one has a link or scripts for doing this I would be much appricated, Thx

Hi,
You are only seeing 15 rows as your table is not correct after entry 15. From row 16 onwards you need <td></td> for each column even if you have no entries to ensure the Spry HTML dataset picks up all the rows.
Try the following on your site in same directory as your PHP page to see how it works on a simple page. Change references to folders for SpryData and SpryHTMLDataSet as appropriate

How to display the sorting arrows in the table column header

Hi
I am doing a sorting for some columns from the click of the table column headers, In Developer studio, we are able to view the up and down arrows, I need that also to be made visible at run time, so that the user knows that there exists sorting based on that particular column. Is there any other way of doing it ? I cant place more than one control on the header or wrap the text to two lines..also. please clarify. thanks

I assume you are using NW 04.
The table column header contains a IWDCaption element which may display an icon and a text. See property IWDCaption.imageSource.
The table tutorial might also be helpful.

Basic Template tutorial

Suggestions for an easy to use basic template tutorial?
1) Specifically I want to create a template with a navbar
similar to this one:
www.mulberrywood.com
2) Without the center text and images
3) And with the bottom text links to other pages.
For some reason when I manually copy the text links at the
bottom of the page they never link correctly... I have to use the
link box at the bottom of the page to erase the link and then paste
in the link and then they always work...

> I am seeking a very easy to follow tutorial (preferably
with step by step

others) myself.
Did you read the tutorial at the dw template tutorial link I
supplied?

I'm not exactly sure you are having the copy and paste
problem, but I would
assume it's because the links aren't being recognised
correctly.
Ok, I'll give you the steps to take to create a template from
that mulberry
page.
Make sure the page you want to create a template from is
correctly coded,
the links are correct, the links to graphics are correct
extra.
1.Open the site you want to work on. ( you need to be working
in a defined
DW site for templates to be created correctly
2.Open the index page (which is the one I presume you want to
create into a
template).
3.Leave everything as it is.
4. Go to FILE>SAVE AS TEMPLATE
5. You will get a dialogue box..
with the Site box already filled in (should be the name of
you defined site)
Save As: give your template a name (eg: mainpage)
Save
6. You will be asked to update links. Say yes
7. You now need to create an editable region (this is the
area that you
will be changing on every page).
8. Highlight the center table in your content area
9. Go to : INSERT>TEMPLATE OBJECTS> select Editable
Region
10. Dialogue box: Name: maincontent (or whatever you want to
call this
editable region)
11. Click OK
12. You have now created a template.
the code around your table should now look like this:

<table> bla bla bla </table>

13. Now if you want to create a 'child page' from this
template go to:
FILE>NEW> and select the TEMPLATES tab
You should now see the name of the template you create.
13. Select the template and a page will now be created for
you.
You should now see a page exactly the same as your index page
(if that is
what you used to create the template), except that you can't
change anything
in any area apart from that middle table.
14. You now need to save this page.
SAVE AS: services.html (or whatever).
Make sure you save the file to the root of your folder (where
all your other
files are kept, DO NOT save into the template folder) You are
not to have
anything in the Templates folder apart from the dwt file.
15. Your bottom links in your template file (dwt) will look
something like
this:
a href="../howtofoldpocketsquares/pocketsquarefolds.htm"
This is because once the template is created, the link needs
to point to the
root of your site.
When you look at the same link in the child page you created
it will look
like this:
a href="howtofoldpocketsquares/pocketsquarefolds.htm"
That's about it. You cannot however, apply this template to
your other
pages. You can, however, it may be difficult for a novice to
accomplish
until they understand how templates work.
If you managae to create the template, you will have to
create a child page
and then copy and paste the contents from your other pages
into that
maincontent editable region you create.
Another thing to remember is that in your template, make sure
when / if you
add links to make them Relative to: document. This way, your
linking should
always be correct.
For when you want to create a new template at any other time
(not with this
site), the steps are pretty similar. Create your page, save
as template,
add any editable regions you need and follow the steps from
there.
PS: I did notice in your code, that you are using <th>
in your tables
instead of <tr>
<th> is really used for headings, you should be using
<tr> table rows.
When you insert a table, there should be a dialogue box,
where you need to
DESELECT header rows.
Anything that gets put into a <th> gets a bold
formatting, which is not what
you really want when you create a table correctly.
This table tutorial may also be of some help to you:

Phew !! I think that's about it and I hope this helps, at
least a bit ;-)

any standard sap method supporting this feature.
it was explained in table tutorial but iam not finding this type in java native dictionary.
any suggestions to do this if user clicks on table column.
Thanks,
Damodhar.

Hi Damodhar,
If java class is in your project`s class path you can select it as context attribute type in followinf way;
1) create context value attribute
2) select property of new created attribute
3) select "type" property and press "..." button
4) select "java native type"
5) select "browse"

Drawing tables

I am quite new to DW Max and also do'nt know coding. I a retired person using computer as Hobby. I am creating a simple website. I want to draw separate tables side by side. Is it possible if yes, how?

Please do not use the 'draw a table' in layout mode... it will give you a false sense of security and will create a fragile page layout that will break.
I realise that you don't know any coding as yet, but it may be worthwhile learning a basic understanding of html and css before you begin your journey wtih Dreamweaver.
You can't really place two separate tables to sit side by side because there would be a tendency for one of the tables to 'fall below the other one' once you start inserting content. The important thing to remember about tables and cells is that the will shrink or expand depending on the content inside them.
I found this fairly simple table tutorial that may help you get started:
http://webmaster.appstate.edu/support/beginning_dw/tables.htm
You mention DW Max, not sure what version that is, unless you mean DWMX? It is a fairly old version by today's standards, and does have tools in the interface that you shouldn't really use - one of them being 'layout mode' - as explained above :-) Also, do not get drawn into using 'layers' - in the early version you were able to 'draw' these as well - stay well away from that!
On a side note - these days there is the tendency to move away from tables for layout purposes, and use CSS layouts instead - if you want to take a look at this type of layout.. here's a few tutorials that may help:
http://www.macromedia.com/devnet/dreamweaver/articles/css_concepts.html
http://www.adobe.com/devnet/dreamweaver/articles/table_to_css_pt1.html
Hope the above tutorial will get you going - if not, post back with any questions you may have.

How to initilize the size of rows in an jtable in run time

i am trying to retrieve data from a oracle database and display them in an jtable ,but i could not figure out how to increase the size of the table based on the number of records fetched in runtime. i also want to add checkbox for each enrty made in the jtable such that by cheching the box ,i could select the data and process it in futher frames. i use an netbean5 version for design.kindly give me giudence.

Best thing to do is write your own table model and a Cell Renderer for the check box.
Please follow the "How to use tables" tutorial.

Updating JTable Contents

I'm having trouble refreshing a JTable after changing it's 2D Object array data. Perhaps this is a stupid question, but any advice would be appreciated.
Basically I've been building from the SimpleTableDemo.java file in the "How to Use Tables" tutorial. I set Object[][] data to a 2D Object array that is modified by other parts of my program.
I added the public void tableChanged(TableModelEvent e) function to detect data changes, displaying a simple System.out, but it never seems to get called.
Is there any way that the JTable can observe changes in the Object[][] data array and update it's self accordingly? I'm never sure if rows are being added or removed.
I hope that made sense, and thank-you in advance to anyone who replies.
-Arthur

Couple of things...
Whenever you change the contents of your TableModel you need to fire the appropriate event to get the JTable to update the viewed rows... in your case it sounds like you would have to call the "fireTableDataChanged()" method defined by AbstractTableModel so that your contents will be viewed.
Also... it is rare that you really need to update the entire contents of your table model, most the time it is more efficient to just update the cell or row your need and call the appropriate "fire..." method to update
Hope this helps

Setting the backgroundcolor of cell of JTable

Hi
My Problem is.
I have a JTable with 2 columns ( Rows can be 1-10 depending upon the size of
input vector)
I have provided two button in my Frame
1)Update Row
2) Update whole Table.
Now i want I want that if a user makes a change in any cell say cell( row
3,Col 1) ;and moves to next row , then the color (background/foreground) of
that cell should change to any other color .Again if he presses any of the
button then the default color of the cell should be restored.Basically i
want to indicate the user that he has made changes in the cell and he needs
to press the button for updation
Regards
Aminur

You need to write your own TableCellRenderer if you want to control how individual table cells appear. Look in the How to Use Table tutorial if you haven't already done that; you'll find a link to it in the API documentation for the JTable class. And in that renderer, if you use a JLabel to render the cell, remember that a JLabel defaults to being transparent, i.e. you can't see its background. Use "setOpaque(true)" if you want to control the background colour.

Booleans not rendering as JCheckBoxes in JTable

I've read several posts on trying to get JCheckBoxes to render in a JTable, and I've looked at the Tables tutorial, but I still can't figure out why my JTable isn't rendering Booleans as check-boxes. :-(
I thought rendering check-boxes was the the default behavior for cells with Boolean values. This doesn't seem to be the case. I can add a cell editor of type JCheckBox by simply instantiating a new DefaultCellEditor, but adding a cell renderer doesn't look so easy (I believe I have to create my own implementation class). I was trying to avoid that, because a) I'm working in Servoy (which means I'm working in a Rhino editor and need to access my own custom classes as plugins or beans), and b) my Java skills are weak.
So can anybody see anything about my code that is obviously wrong? Or do I have to roll up my sleeves and write my own DefaultTableCellRenderer bean/plugin?
Here's my code (remember - it's javascript instances of java objects). (Note: I'm not sure exactly what kinds of objects JSDataSet.getAsTableModel() returns to the JTable model, but creating my own JTable with a vector of vectors of Boolean objects, or setting a Boolean in the cell after the fact doesn't work either.)
Any tips would be greatly appreciated.
// convert dataset into JTable
var table = elements.monitoring;
table.model = treatments.getAsTableModel();
// modify column headers
var columns = table.columnModel;
columns.getColumn(0).setHeaderValue('Quantity');
columns.getColumn(0).setPreferredWidth(60);
columns.getColumn(1).setHeaderValue('Repeats/hr.');
columns.getColumn(1).setPreferredWidth(75);
columns.getColumn(2).setHeaderValue('TREATMENT');
columns.getColumn(2).setPreferredWidth(225);
// start treatment times at 8am
var j=8;
for (i=3;i<44;++i) {
     var j_int = Packages.java.lang.Integer(j);
     columns.getColumn(i).setHeaderValue(j_int);
     columns.getColumn(i).setPreferredWidth(10);
     if (j == 12) {
          j=0;
     ++j;
// center cell data
var cell_class = Packages.java.lang.String;
var table_renderer = table.getDefaultRenderer(cell_class);
table_renderer.setHorizontalAlignment(0);
// add JTable to JScrollPane viewport (necessary to display headers)
var viewport = elements.monitoring_pane.viewport;
viewport.add(table);

Ok, another problem -
I wound up throwing out the Rhino constructor method and implementing my own JTable class and importing it into the Rhino scope. I had to do that because I needed columns to render different types of objects - basically, the table cells should appear blank until they are selected and data is added to them, at which point they should be Boolean and render check-boxes - I got that to work by overriding the getCellRenderer method.
The problem is, I need to add some logic to the 'onClick' event for the table cell, so that I can add a blank check box, add a checked check box, or remove a check box. I looked at the Table tutorial and tried to do it by implementing the TableModelListener interface on my JTable and defining the tableChanged method. However, when I add the tableChanged method to my class, I get an ArrayIndexOutOfBoundsException.
Any tips would be greatly appreciated.
I instantiate the class in Rhino and add the TableModelListener like so:
var table = new Packages.my_classes.MyJTable();
table.model = model; // a working model defined elsewhere
table.getModel().addTableModelListener(table);Here's my class:
package my_classes;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.event.*;
public class MyJTable extends JTable implements TableModelListener {
     public TableCellRenderer getCellRenderer(int row, int column) {
          Object value = getValueAt(row,column);
          if (value == null) {
               return getDefaultRenderer(JCheckBox.class);
          return super.getCellRenderer(row,column);
     public Class getColumnClass(int column) {
          if (column > 2) {
               return Boolean.class;
          } else {
               return Object.class;
     public void tableChanged(TableModelEvent e) {
          int row = e.getFirstRow();
          int column = e.getColumn();
          TableModel model = (TableModel) e.getSource();
          String columnName = model.getColumnName(column);
          Object data = model.getValueAt(row, column);
}

Images in some Column-Heads are not visible

Hi there,
in an Webdynpro-Application I am using tables that are sorted in that way that is discribed in the Tables-Tutorial (with TableSort-Class). Everything works fine except that initially there is no image in the column-head although I set one in the layout-designer. After sorting the apropriate images appear.
I tried to set the image-source again, I tried to set the image in the source like:
<i>IWDTable table = (IWDTable)view. ...
table.getColumns()[...].getHeader().setImageSource("...");</i>
... doesn't work.
Are there solutions? Thanks!<i></i>

Hi,
Your code is right. but i think you have placed the setImageSource code before the call of Table Sorter class.
if you put that code after the object creation of TableSorter class, it will work.

Karthik

Jtable with html in a cell

Hi,
Somebody can tell me how can i put a Jlabel with html in a Jtable cell. Is that possible ?
Tks.

you need to implement a TreeTableCellRenderer
and add the renderer to your table.
check the Java tutorial on table
forgot the link..so you gotta google the link "java Table tutorial"

About hiding columns in a JTable.

I have read various ideas on how to hide columns in these forums,. Everything from using the removeColumn method in TableColumnModel to writing a wrapper TableModel to handle the details. These ideas work, but in certain situations it is difficult to retro-fit the code in this manner. Being that Swing has a MVC architecture, does it not make since that I should be able to alter the view ( The Table ) any way I like without altering the underlying models? Does anyone have a good solution?
I already had implemented a TableModel which does this, and a TableColumnModel. Probelm is, I have external libraries that make extensive use of the DefaultTableColumnModel in the JTable, and I would rather not have to alter it. those libraries.
Thanks.
AC

Being that Swing has a MVC
architecture, does it not make since that I should be
able to alter the view ( The Table ) any way I like
without altering the underlying models? Does anyone
have a good solution?I can see your point, but JTable presents the view it does which is customizable in certain ways only.
The hiding of columns just isn't part of what it does.
So you could extend JTable to add such functionality. Having looked at the source of JTable recently, I wouldn't want to do that.
The alternative is to wrap existing models in another model that does some transformation (i.e. hiding a column) without changing the underlying model. See the TableMap and TableSorter examples in the Swing Table Tutorial to see an example of this.
