This is similar to Alternate grid background color in excel when a value of a single column changes? , and I believe it can be done using
SUBTOTAL(109,... , but I can't quite figure it out.
The first column in my table is a group number, and all rows with the same group number should have the same background. The table is sorted by the group number.
I want to alternate the row color per group, based only on the visible rows. In this example I've hidden
C . Note that
libero have swapped colors based on the visible rows.
I'm free to add in hidden helper formula columns, but I'd prefer it all to be in the conditional formatting.
