[jQuery] Datagrid

Hello. I need advice as to what Datagrid component to use.
I need one that supports JSON, and it's considerably updated. Also
could use the update, add and delete functions.
I seem to have a hard time finding a good library to do Grid work.
Ingrid doesn't do it for me and Flexigrid is dead and doesn't work
with JQuery 1.3.2
Any ideas are more than welcome!
