The datagrid is an extremely fast and easy way to show a table of records. What is the easiest way to provide summary info on the same web form as a datagrid? for instance:

rec 1 John $7
rec 2 Bill $3
rec 3 Tom $1
_______________
Tots 3 $11

If not with a datagrid, what is the best way to create reports w/ summary info BETWEEN rows of a data grid? Maybe even like this:

NY rec 1 John $7
NY Tot 1 $7
NJ rec 2 Bill $3
NJ rec 3 Tom $1
NJ Tot 2 $4
_______________
Tots 3 $11

All I've figured out so far is how to do this w/ a datagrid:
rec 1 John $7
rec 2 Bill $3
rec 3 Tom $1

Please help!
