Currently our application has a stored procedure that returns a list of clients and a list of client services each has received in the past year. The rows representing each service are grouped by individual, and vary in number from 1-10. (One individual may have only one row , whereas others may have any number up to 10). A unique system identifier (numerical) is used for the grouping. For ease of identifying the rows for a given individual, I would like to alternate or change the background color to indicate the individuals listed.
