They were actually gridlines. "All Borders" didn't work; however, I was able
to create borders through the "More Borders" option. Still wanting to know
how to reestblish those gridlines.

Were they gridlines or actual cell borders? I'm betting borders. Try this:

Select all of the cells without borders and then on the Home tab, click the
down-arrow in the box just to the right of the B I U (bold italic underline)
icons, there is an option in that group for "All Borders". Click it and see
if things improve for you.

I accidently deleted a section of gridlines in Excel 2007. How do I make
them reappear? Selecting the section and activating View Gridlines doesn't
work.
