Add shaded background to every other row of a report

The only catch to Marks recommendation above is that the coloring would fall apart if a user applied their own dynamic filters. The formula query is great to the point above to essentially mimic the report behavior and color accordingly - but the query won't adjust/update when records are removed from searching or using dynamic filters. So for example if you have all the odd rows showing and then you apply a filter that removes the first 10 'even' rows - then the first 10 after you filter would all be odd and would all be the same color.
