Row with one cell in JTable
I have a JTable with multiple cells per row. However, in-between some rows, I would like to have a header row which doesn't change as I scroll horizontally. Is that possible?
Another question about JTables: Is it possible to have fixed cells on the right as well as on the left, with some cells in-between which you can scroll?

Select or deselect multiple rows with one single selection event
Does anyone know how to create a JTable which can select or deselect multiple rows with one single selection event in JTable. Fore example, if the table has
row1
row2
row3
row4
row5
row6
What I need is when user select row1 or row2, both row1 and row2 should be set to be selected. Then if user press CTRL and click one of row3 or row4, both of them should be selected including the previouse selected row1 and row2.
For deselection, if row1 and row2 are selected, when users deselect one of row1 or row2, both of them should be deselected.
Hopefully someone can give me a hint.Here is a partial solution using a JList. Only one line gets highlighted when the user makes a selection in the list. But, two lines are returned. There is a blank line between every two lines.
private void addLineToList() {
String a = f_one.getText();
String b = f_two.getText();
if (a.length() == 0) {
Utils.showInformationMessage("Item field is empty.");
f_one.requestFocusInWindow();
return;
if (b.length() == 0) {
Utils.showInformationMessage("Match field is empty.");
f_two.requestFocusInWindow();
return;
model.addElement("item: " + a);
model.addElement("match: " + b);
model.addElement(" ");
int size = model.getSize();
pairList.setSelectedIndex(size - 3);
f_one.setText("");
f_two.setText("");
f_one.requestFocusInWindow();
private void editList() {
if (pairList.getSelectedValue().toString().equalsIgnoreCase(" ")) {
Toolkit.getDefaultToolkit().beep();
f_one.requestFocusInWindow();
return;
if (!f_one.getText().equals("")) {
int result = JOptionPane.showConfirmDialog(this,
"The Item field contains text. Replace the text?",
"Flash Card Activity", JOptionPane.YES_NO_OPTION,
OptionPane.INFORMATION_MESSAGE);
if (result == JOptionPane.NO_OPTION) return;
if (!f_two.getText().equals("")) {
int result = JOptionPane.showConfirmDialog(this,
"The Match field contains text. Replace the text?",
"Flash Card Activity", JOptionPane.YES_NO_OPTION,
JOptionPane.INFORMATION_MESSAGE);
if (result == JOptionPane.NO_OPTION) return;
String item = "";
String match = "";
int index = pairList.getSelectedIndex();
String choice = model.getElementAt(index).toString();
if (choice.startsWith("item")) {
item = choice;
match = model.getElementAt(index + 1).toString();
model.remove(index);
model.remove(index);
model.remove(index);
else {
item = model.getElementAt(index - 1).toString();
match = choice;
model.remove(index + 1);
model.remove(index);
model.remove(index - 1);
int size = model.getSize();
if (size > 2) {
pairList.setSelectedIndex(size - 2);

How to hide rows with merged cells?
I would like to know how to hide rows on numbers with merged cells, could do it normally at excel but I am not being able to do it at Numbers.
thanks!Felipe,
To hide a row with Merged Cells, Un-Merge first, then Hide. Select the Merged Cells and Table > Unmerge.
Note that this is only a problem with vertically merged cells when you want to Hide a Row.
If you want to Hide a Column, you can't have a Horizontal Merge that involves that Column.
Jerry -
How can I hide columns that has rows with merged cells?
I'm making a schedule on Numbers and there are couple of rows that are one cell (merged).
Because of this reason when I select a column to hide, it's not just the column that is being selected but the column and the all the merged cells that goes across the row. I would like to hide selected column to print different columns. Please help me! thank you!There is even more powerful tip.
Double click in a cell
Show Rulers
Insert a "center tab"
move it to the right edge of the cell
type option + tab then your wanted string.
You will get that :
Add this tip to the drawbacks of merged cells and you will understand why I never used them.
Yes, it may be surprising but the right tab belongs to the cell D2 !

Associating/linking whole rows with individual cells
I have a tracking document with multilple tables within the same document. The first table is a summary sheet. When I make changes to this table I would like the changes to take effect on all subsequent tables.
I have, with help on here, made some progress using the INDIRECT command done this.
However I want the whole row to change position with the cell containing the INDIRECT command.
Any ideas?????

Returning two rows with one column containing only one place
Dear all;
I have a query that returns two rows similar to this below
ID PLACE PROGRAM
A NEWYORK PROGRAM A
A NEWYORK PROGRAM B
I would like this instead
ID PLACE PROGRAM
A NEWYORK PROGRAM A
PROGRAM B
All help is appreciated. Thank you.Edited by: user13328581 on Mar 22, 2011 11:52 AMuser13328581 wrote:
WOW...THanks a lot Solomon, I have never used partitions and row_number in such a manner...can you please explain your logic.Sure:
row_number() over(partition by id order by place,program)This will take all rows returned by the query andsplit them into buckets (partitions) by id. Inside each bucket it will order rows by place and program and assign them row numbers. So for each ID row number 1 will be row with first (alphabetically) place first programt. And this is the row where we want ID to show up. That is why we wrap the above analytic function in CASE statement which will do exactly that. Now:
row_number() over(partition by id,place order by program)does pretty much the same just bucket is ID and PLACE combination. So for each such combination we want to show only for the first (alphabetically) programt.
Now notice in ORDER BY clause I prefix ID and PLACE with table alias. You must do it since otherwise query alias ID and PLACE will take precedence resulting in wrong sort order (remember we nulled all ID and PLACE except for row number 1).

Removing rows and inserting new rows with new data in JTAble!!! (Plz. help)
I have a problem, The scenario is that when I click any folder that si in my JTable's first row, the table is update by removing all the rows and showing only the contents of my selected folder. Right now it's not removing the rows and instead throwing exceptions. The code is attached. The methods to look are upDateTabel(...) and clearTableData(....), after clearing all my rows then I proceed on adding my data to the Jtable and inserting rows but it's not being done. May be I have a problem in my DefaultTableModel class. Please see the code below what I am doing wrong and how should I do it. Any help is appreciated.

#####################################The following code works fine but it doesn't show me the new updated date in my JTable. I tried to print the values that I am getting and it does give the values on the prompt but doesn't show me on the JTable only first two are shown and the rest of the table is filled with the same values. I don't know what's going on and am tired of this TableModel thing so pla. take a time to give me some suggestions. Thanks

With one cell with text, make 2 cells with 2 texts
Hi,
I have one column with first name and last name in a same cell (like 'Laurent Didden')
I would like to transform automatically one column in 2 columns where one column will be with the first name, and the second column with the last name.
How can I do that?
Thank you for your help...
Pat.Pat,
Excel may have that function, I'm quite sure that Numbers does not. Numbers is in its first version and is not a clone of Excel in any case. The functions are not so complicated as they may seem.
FirstName function translated into English is:
If the WholeName is blank, Then leave the FirstName cell blank; Else put here the Left portion of WholeName, up to one character less than the position of the first Space Character you find in WholeName.
The LastName function translated into English is:
If WholeName is blank, Then leave the LastName cell blank; Else put here the Right portion of WholeName, the number of characters equal to the total length of WholeName minus the position of the first Space Character in WholeName.
Hope this helps. Good luck.

Content Conversion: One row with one header and multiple item structures. Possible?
Dear all,
I have a input that looks like this:
HeaderKeySomeHeaderInformationItemKeySomeItemInformationItemKeySomeItemInformation...
Here's the actual input
TEHGMESS0026000000288S0001TEI2____026200006112410400000000 18010000000000 00126000000000126000120600000000002000000000 000WESTMONOBERTBE2014052309422408120003 000000000000000000000000000000JTEI2____026200006112410400000000 19010000000000 00126000000000126000120600000000002000000000 000WESTMONOBERTBE2014052309422408120003 000000000000000000000000000000J
HeaderKey = TEHGMESS
ItemKey = TEI2____
Is it possible to process this via MessageTransformBean (my actual scenario is JMS to IDoc)? I already tried but I only succeeded when having new lines in my input to separate between Header and (multiple) Items.
So when the input and my configuration looks like below it works, but when I only have a single row input it doesn't work, even when specifying xml.recordHeader.endSeparator = '0' / xml.recordItem.endSeparator = '0'. I even tried xml.endSeparator = '0' but no luck.
Input that works
TEHGMESS0026000000288S0001
TEI2____026200006112410400000000 18010000000000 00126000000000126000120600000000002000000000 000WESTMONOBERTBE2014052309422408120003 000000000000000000000000000000J

Any clues on this? Is it even possible to have multiple structures in one row? Many thanks in advance
JensSAP came back to me with this answer:
First, I would like to point the documentation for Message Transform
Bean (MTB) in 7.4:
http://help.sap.com/saphelp_nw74/helpdata/en/57/0b2c4142aef623e10000000a155106/content.htm?frameset=/en/57/0b2c4142aef623e10000000a155106/frameset.htm¤t_toc=/en/45/0ea2de423c2d6be10000000a11466f/plain.htm&node_id=18
As it is written at the beginning of this document, MTB is used to
call classes written for the Plain Adapter Engine. So you may find
additional documentation about the parameters for convertion in the
documentation of the Plain Adapter Engine
(http://help.sap.com/saphelp_nw74/helpdata/en/0d/00453c91f37151e10000000a11402f/content.htm?frameset=/en/1b/d5ef3b1ad56d4fe10000000a114084/frameset.htm¤t_toc=/en/75/246b3de666930fe10000000a114084/plain.htm&node_id=11).There it is written that the structures by default are
arranged line-by-line. The endSeparator just adds additional character
string as a separator after the last column in a row.
I hope that this answers your question. MTB expects the data to be
structured line by line.
You may add a custom module, which transforms the message in the
expected format.
If you have a look at the second link there's even a more precise wording that multiple structures within one line are not supported:
xml.NameA.endSeparator
Even if no specification is made here, a line break must follow since substructures are always expected as a line of the document.
Bottom line is that it's not supported by now and verfied by me with PI 7.4 SP5
Many thanks to Ambrish, Amit and Hareesh for the valuable input. Will probably try to work things out for now following Ambrish's / Hareesh's suggestion as this seems easier to implement. Amit's proposal with a dedicated module however would probably be the more polished solution.
Cheers

Hiding rows with parent cell having rowspan
hi experts,
i have a table with column 1 being the parent declared with rowspan = 2 and the next column having 2 rows. an example is below:
parent row | row 1
| row 2
i would like to hide the second row only in column 2 in such a way that the output would be as follows:
parent row | row 1
it is a bit difficult in this case as the parent row is declared having the rowspan=2 setting. does anyone know how i can hide the second row or collapse it? i am able to hide row 2 with the 'display:none' option, but since the parent is declared with a rowspan of 2, i am getting a grey line below row 1. any help would be highly appreciated!
markYou're reinventing a wheel that's been done a few times. One example is JTreeTable (http://community.java.net/javadesktop/) but there are others.

Insert multiple rows with one sql statement in access
Hi,
I'm trying to copy a table into another. What I want to do is to use "Insert into table1 select * from table2 where field > val". Something like that. I know a lot of databases support it. I was wondering if ms access ODBC driver also supports it. I searched quite a bit and haven't found a definitive answer on this.
Thank youYes, M$ Access 2000 supports it. This is from their help:
INSERT INTO Statement
Adds a record or multiple records to a table. This is referred to as an append query.
Syntax
Multiple-record append query:
INSERT INTO target [(field1[, field2[, ...]])] [IN externaldatabase]
SELECT [source.]field1[, field2[, ...]
FROM tableexpression
Single-record append query:
INSERT INTO target [(field1[, field2[, ...]])]
VALUES (value1[, value2[, ...])
The way you've written the INSERT, table1 and table2 have to have the same # of columns and the same types, of course. -
Plz some help me out ......i want to merge two consecutive cells of a row in one cell in JTable......... how to do that.....give some code if possible....
Well, as a new member you should learn to search the forum first before posting questions. Using keywords like "jtable merge cell" will find other postings on this topic. Some with solutions some without, so you will need to read a few and decide on the approach you want to take.

How to create CSV data with a cell including two rows?
Hi guys,
i am creating CSV using "comma" as seperator for columns, "return" as seperator for rows.
But how can I create a cell which includes two rows?
I want to do following:
cell1 cell2 cell3
XXXXX YYYYY ZZZZZ
in cell2 YYYYY, there are two sub rows:
YLine1.1 YLine1.2 YLine1.3
YLine2.1 YLine2.2 YLine2.3
Which kind of seperator can I use for these sub rows?
so to say(XML mode):
<row>
<Col1>XXXXX</Col1 >
<Col2>
<row>
<col1>YLine1.1</col1>
<col1>YLine1.2</col1>
<col1>YLine1.3</col1>
</row>
<row>
<col1>YLine2.1</col1>
<col1>YLine2.2</col1>
<col1>YLine2.3</col1>
</row>
</Col2 >
<Col3>ZZZZZ</Col3 >
</row>
It is very kind of you to give me some hint!

Liying

I tried with Excel. A Cell with 2 rows saved as CSV shows that the cells contents are enclosed in hyphens "b row 2 b" and the two rows ins one cell are separated with HEX 0A. This is a simple Line feed. The sequence to build this would be in ABAP
concatenate
<row1>
CL_ABAP_CHAR_UTILITIES=>NEWLINE
<row2>
into cell.
I did not take the time to try on system, but I tried to open with excel: It works with Windows.

Clemens
