I've got a spreadsheet with about 80 columns. Auto-filter works fine, except
that it excludes certain columns. The excluded columns are text, and are
fairly wide (150 bytes, 240 bytes, 640 bytes).

Even though the text in these columns is quite wide, I still want to filter
them so I can use criteria such as "begins with" or "contains".

Is there any way to apply a filter to these columns?

Thanks.
