lost gridlines excel 2000

I found that someone else had the same problem in a closed thread. I had created a spreadsheet and had increased the size of the cells. When I tried the remedy suggested--go to format>view>pattern tab and click on No Pattern, what happened was that gridliness were restored but at the original size not the size of my new cells (in the areas I designated for restoration.

I would simply like to restore gridlines to the spreadsheet to conform to the expanded size of the cells as present.

Thanks,

Mark
