Hoping someone here can help me figure this out.

I need to have two seperate and independent column widths for the same
spreadsheet. Such as this:

Top Portion of Spreadsheet
[-----------][---------][----------------]
Bottom Portion of Spreadsheet
[-----][------------------][------------------]

The column width of each portion needs to not affect the other portions
of the spreadsheet. Merging cells would be too time consuming. Any
assistance would be appreciated.
