There is probably a way to to it by some column size manipulation (you
can "hide" a column by settings its size/width to 0), but I don't see a
compelling reason not to use two separate table viewers. There is really
no significant resource usage unless you have LOTS of viewers or LOTS of
rows or LOTS of columns (by LOTS I mean hundreds or thousands).
It really seems like a much simpler solution than trying to manipulate
the columns; I always strive for small, simple classes that do one thing
well, rather than complex ones that try to do a lot.
Hope this helps,
Eric

org.eclipse.swt.custom.StackLayout is exactly what you want. See the
example code in the class Javadoc.
Hope this helps,
