Answer 1

I have found a simple solution to banding by content at Pearson Software Consulting: Let's say the header is from A1 to B1, table data is from A2 to B5, the controling cell is in the A column

1. Make a new column, C
2. At first the first row to color make the formula =true in the C2 cell
3. In the second row make the formula =IF(A3=A2,C2,NOT(C2))
4. Fill the column down to the last row
5. Select the data range
6. Select conditional formatting, choose Use a formula... and put =$C2 as the formula
