I have a large spreadsheet that I'd like to use conditional formatting on the
rows. I've seen examples on how to apply it to every other row, but in my
case, I have groups of data that remains together in blocks of 8 rows each
(this is consistent). The other issue, is that I want the formatting to
start on row 6 (the consistent blocking starts on row 7). I often need to
insert another "block" into the spreadsheet and find myself re-formatting the
cell shading all throughout the spreadsheet.

Any ideas on how I could use conditional formatting to make the first block
of 8 rows white, next 8 grey, next 8 blue and then repeat the conditional
formatting?





row 1 headers
rows 2 & 3 blank
row 4 (headers) Month, Footage
row 5 (headers) Customer Building, HDD, Customer TYPE
rows 6-13 8 data rows (want them white)
rows 14-21 8 data rows (want them grey)
rows 22-29 8 data rows (want them blue)
repeat this conditional formatting on the color
