Suggestion for a nice grid?

Suggestion for a nice grid?

Hello all,
I am prototyping a project and need a cool grid to play with and use.
Can anybody suggest something good and with clear documentation?
Needless to say, it shall be fully supporting AJAX (remote crud).
Ideally, the grid I am looking for has the following features:
- Integrated with latest JQuey UI (theme support)
- Draggable columns
- Filters
- Double sorting (local and remote, I want to be able to )
- Footers
- Display/Hide grid columns(f.i. I want to keep the ID column but
unwilling to display it!)
- Inplace editing
- Read-only mode
- Collapsible (showing headers only when collapse icon clicked)
- Keyboard powered
- Usable incrementally(i.e. read only first, add support for remote
data deletion, then insertion, etc)
Also, ideally I would want to be able to use two models in a single
grid: one describing the column data
while the other feeds actual data in. This would allow me to generate
everything on the fly.
Any pointers/suggestions?
Thank you for your time reading this,
