If ALL of the gridlines have disappeared...Try this:

From the Excel main menu:
<tools<options<view tabCheck: Gridlines

If that doesn't work, or only some gridlines are missing, try this:

Select the impacted cells (or the whole sheet)
Then
From the Excel main menu:
<format<cells<patterns tabColor: No color
or
From the "fill color" button on the Formatting toolbar...select "No Fill"

Does that help?
