multiple data sets in a single grid

I have come across similar posting but not the same.

Here is the problem. I have three datasets which have the same headers but say 10 rows of data for each. I need one grid which would have the first header, first data set and the first footer then the second header, second data set and the second footer and for the third one too.

The advantage of doing this is, I can maintain one grid but many data sets which is dynamic and the grid would have fixed columns. The most important feature is sorting on a dataset by clickin on its respective header.

Any ideas?

Thanks,
