Crystal Reports Question

I have created a basic table using Crystal Reports 8.5. I would like to enhance the table’s formatting by adding a color background fill for every other row. In other words, the first row has a green background fill, the second row is plain white, the third cell has the green fill, the fourth row is white, etc.

Unfortunately, I have so far been unable to find a way to do this in Crystal Reports. It seems to be easy to make either all or none of rows have a background fill, but not the alternating color scheme I am looking for. Also, I can?t use the cross-tab feature because the table has only column headings and no row headings — so this is not an option.

Could someone please give step-by-step instructions on how to add the alternating background color fill feature if they know how? Thanks
