I want to confine a sheet in my workbook to just one page. Basically, when
the workbook is opened, it is a coversheet of sorts, and I only want it to be
one page. How do I "remove" all of the columns and rows that I don't want
seen? (Not "hide", but rather there is my information in the white area, and
then there is all the grey space that isn't going to be used around it.)

I've seen it done, but can't recall how to do it.
