Welcome!
Two plugins that come immediately to mind are jqGrid and Ingrid. If you look in the plugins page at jQuery.com, you should be able to find the details for both plugins.

I am new to jQuery, but I am quite excited about discovering it. Already I have made big gains in productivity at work. I would like to ask what are the "best" grid plugins that I should consider using? By best, I don't mean wealth of functionality. I just mean well-written, with a good interface. Solid code. Thanks.
