Hello,
After trying the GroupableTableHeader example found at:

http://www.objects.com.au/java/examples/swing/GroupableTableHeader.do

and after correction of 2 lines in GroupableTableHeaderUI.java:
-> In the paintCell method, replace the line:
   TableCellRenderer renderer = aColumn.getHeaderRenderer();
by:
   TableCellRenderer renderer =
header.getTable().getTableHeader().getDefaultRenderer();
-> In the getHeaderHeight method, replace the line:
   TableCellRenderer renderer = aColumn.getHeaderRenderer();
by:
   TableCellRenderer renderer =
header.getTable().getTableHeader().getDefaultRenderer();

Everything works fine with a JVM 1.4, but when I try it with a JVM 1.5
I never got the Group-Columns... It looks as if the paint method of
the UI
is never called under 1.5...

Has anyone got the same problem ?
And if yes, is there a solution to correct it ?

Thank you for any help...
