What grid to use??Confused

[eluser]imtiazhashmi[/eluser]
im looking to use a Grid in PHP CI (1.7.1).

i have searched Flexigrid , it works but , im not able to get Edit/Add things working inside the grid.
i have seen YUI and ExtJS (not used yet) , looking upon them as options.
can someone suggest me something really tested , that works fine with CRUD inside grid.
All the searches on these leads to different problems , may be those who Solved dont Post.
thanks a lot
