Java Development Tools

Using JDev 11.1.1.3 created an EmpVO using all eight columns of data.
Drop the data control on to a view component (view-document) and the entire table is rendered - all eight columns.

Now comes the problem!
Add a button and the table is now constrained to the upper left portion of the view and displays only the first three columns. Then place the table in a stretch layout component (Panel Stretch Layout, Decorative Box) and now can get the first five columns displayed and no more - no matter how wide the browser window is! In both cases do get appropriate scroll bars. How do I get the entire eight columns to display? Have plenty of browser width but no matter how wide I stretch the browser window I still can get only the first five columns of the emp table displayed. If scroll can see the remaining three columns but never the entire eight columns.

Next question - why does the table occupy the entire window when no other components are present - see the same thing when add a single button to a splitter pane or example. Add a second button and both buttons will display in their 'standard' size.

Thanks or the clarification - Casey
