Another way is to hide them using conditional formatting. Highlight
the cells you want to be affected in this way, then Format |
Conditional Formatting, then choose Cell Value Is, Equal To, 0 (zero),
then click the Format button and choose a foreground colour of white,
then OK twice. The cell will appear to be empty (white on white), but
the zero (and formula) is still there.
Hope this helps.
