Flexigrid – Web 2.0 Javscript Grid for jQuery

Lightweight but rich data grid with resizable columns and a scrolling data to match the headers, plus an ability to connect to an xml based data source using Ajax to load the content.

Similar in concept with the Ext Grid only its pure jQuery love, which makes it light weight and follows the jQuery mantra of running with the least amount of configuration.
