[jQuery] Adding Values (Sum) of TD.

[jQuery] Adding Values (Sum) of TD.


I am trying to do a footer at the bottom of the table, and I would
love to use jquery to provide a total in the footer, something like
this:
1 | 1 | 3
2 | 1 | 4
----------
2 | 2 | 7 (JQuery added the TDs above)
Is it possible? And can anyone point me in the right direction.
