If you use conditional formatting, you can set up the following 3
conditions. All use the "Formula is" option.
Condition 1 =ISBLANK($A16) with No format set
Condition 2 =MOD(ROW(),2)=1 format this colour for ODD rows
Condition 3 =MOD(ROW(),2)=0 format this colour for EVEN rows
The purpose of the first condition is to leave blank rows un-coloured.
If you only want to colour ODD (or EVEN) rows whilst leaving the others
uncoloured you can use condition 1 and condition 2 (or 3)only.
If you don't mind about having blank rows being coloured then omit
condition 1.
Hope this helps
