excel中有没有办法对整列应用基于公式的条件格式？

Question

So I have these columns:

And what I would like to have each cell under the "Completed Date" column change color according to whether the date is before or after the due date or if it's blank. I'd like to do it in a way where I don't have to set the conditions for each cell individually but rather in a sort of "drag through" way, like when you use a formula, and you drag that formula down, it applies to each adjacent cell on the way down. Any assistance with this would be most appreciated. Thanks!!

Answer 1

As @cybernetic.nomad says, get it right for the top-left cell and the rest will follow. For example, if you want to highlight where the completion date is after the due date, put

=AND(ISODD(COLUMN()),B2>A2)

as a custom formula.

You will need separate rules to highlight blanks and completion dates equal to or before before the due date.

What happens if your range starts in column A, so there is no column before it? A strange quirk of conditional formatting is that it allows you to wrap it around to the very last column (XFD), so in this case your formula would look like this:

=AND(ISEVEN(COLUMN()),A2>XFD2)
