Sorry I mentioned the Worng Version : I'm using version 1.1 by now.

The following macro works for me:

sub Main
	dim separator as new com.sun.star.text.TableColumnSeparator
	
	' insert table
	xTextTable = ThisComponent.createInstance("com.sun.star.text.TextTable")
	xTextTable.initialize(3,5)
	xText = ThisComponent.Text
	xText.insertTextContent(xText, xTextTable, true)

	separatorArray = xTextTable.TableColumnSeparators
	
	' change column separators
	for i = 0 to ubound(separatorArray)
		separator = separatorArray(i)
		separator.Position = separator.Position / 2
		separatorArray(i) = separator
	next i

	' write separators back	
	xTextTable.TableColumnSeparators = separatorArray
end sub

.

Own Porgramm Testing TableColumnSeperator

Hi sg,

I'm sorry I have to reopen this one.
After several tests I found the situation where it does really funny things.
I Attached my own programm, which is loading an existing Open Office Document
with an existing table named "b4it:spras", this table has 3 columns and 3 rows.
in the second row the first and second cell is merged.
It looks like :    A1  B1  C1
                   A2  B2  C2
                   A3      B3

So even if I try to set the original value of the TableColumnSeparator Position
to the Object it sets every time it is running another value !!! but only in the
 third row !!!!

Hope you can help me out with this one.

Thank you very much

Best regards
Bernhard Diemer

complex test case

Added complex test. To reproduce the bug, unpack the zip and go to
complex/writer, type 'dmake' to build and 'dmake run' to execute.

bug consists of several parts (documentation and code), concerning text tables
with merged cells:
- TableColumnSeparator.idl is not completed, at the end some text parts are missing.
- the invisible text separator between the merged cells is not returnd with the
column separators collection, but TableColumnSeparator.idl states that it should
have been.
- reading the column separators and writing back the same values results in a
changed separator 

Happens on all systems; set target; reassign to tl: one for you.

.

Because the original poster mention this behavior on version 1.1., I want to 
add that I got the same problems using 2.0.2 or 2.0.3., no matter if I use 
Basic or C++.

Especially "reading the column separators and writing back the same values 
results in a changed separator" is very wired.

.

No more issues accepted for OOo 2.4 unless there are serious problems.

Hi, 

tableColumnSeperator works inconsistent. tested version aoo 3.4.1 linux i686

below program show correctly changed tables with 2,4,5,8 and 16 columns while tables with 3,6,7,9,10-15 columns do not:

Code with so many shouldn't be included in a comment, but added to the bug as an attachment.

program showing failure of tableColumnSeperators

still exists in 4.1.3

I can confirm this Bug.

The tablecolumnseparators can be set by a macro in OpenOffice Writer itself.

The same way using -in my case VFP- by API/COM does not work.

Using Xray I can see that the properties of TabbelColumnsaparators are not modified using VFP.

I think the problem exists only in the commnication COM/API.

Hi,

I looked at this example, translated it and it still does not work.

https://wiki.openoffice.org/wiki/API/Samples/Java/Writer/TextTable

Does this example work in Java or other languages?

fails in 4.1.6

No it does not. It uses 10 columns and that's a failing amount. See my previous remarks.
It seems to be an initial setup problem. Workaround is to create a 'good' table first, join columns to get the desired amount. Tablecolumnseperators will than  work fine.

fails in 4.1.15
