Thanks for the comments. After I posted this message, I checked out
the SDK docs and found TblSetColumnWidth(). I'm not quite to the
point where I want to get down to that much detail in the UI layout,
but it's nice to know that it's there if I need it.
Well, back to coding and figuring out more about the Table control.
Again, thanks for the suggestions.
