Datagrid - each item having two headers one displayed by row another by column

[Krishna]

Hi All,

Scenerio: There are many contracts. Each contract has some items for
which the contract has been established. So i have to display the
Rebate on each item of each contracts. There is more complexity
invloved like few items are given a group name but as of now lets focus
on displaying the rebates for each item in each contract. Hope i am
clear, if i'm not following diagram will help u understand:

ITEM -> Item1 Item2 Item3 Item4
CONTRACT
V
C1 2% 3% 2% 4%
C2 0% 2% 3% 5%

Does Datagrid have solution for this? If there is any other alternative
also, Do let me know.

Awaiting quick response.
Krishna
