Use:
table.setLayoutData(new GridData(GridData.FILL_VERTICAL));

        Subject:        [platform-swt-dev] Problem with getting scrollbars to showup on a Table.


Hi, 
I am developing a new ViewPart which will needs to have three Group 
widgets. The first group widget will have a table. The second group will 
have a few buttons, the third group will have a List widget. I can get 
each of the groups to be displayed but I can't get the table or the list 
to show scroll bars. My table ends up being longer than the view window, 
so I need it to scroll.  I would like the table and list to scroll 
separately.
The source code is below for my ViewPart. Can anyone tell me what I need 
to do to get the scroll bars?? 
Thanks 
Bob
