Hi my friends,

The question which I am going to post here was posted on Oracle Java forum about 2 weeks ago. However I did not get any answer so please allow me to re-post it here. Hope some experienced guys can help me.

I want to have my table with a cell spans on two columns, like merged cell in Excel.
I found an example here:

http://www.java2s.com/Code/Java/Swing-Components/MultiSpanCellTableExample.htm

But I were not able to get it works, it throws some exception at runtime:



Any help?

Many thanks,
Nam

some time back this was the fix (unsure if still relevant)

In class: AttributiveCellTableModel,
In method: public void setDataVector( Vector newData, Vector columnNames )

Change the line:
setColumnIdentifiers(columnNames);

To the line:
columnIdentifiers = columnNames;
