Select all the cells (click to the upper left of cell A1), then use Format / Conditional
Formatting... choose the "Formula is..." option and use the formula

=MOD(ROW(),2)=0

or

=MOD(ROW(),2)=1

and set your shading as desired.

So, I am trying to autoformat an excel spreadsheet with every other line
shadowed, or highlighted, or something, so that the lines are easily
differentiated. I was wondering how to go about doing that.
