Compass DataGrid is an ajax-driven data grid jQuery plugin that takes an empty table and populates it by connecting to a server-side url via ajax.
As users interact with the grid, the grid talks with the server-side script letting it know what the user is requesting. The server-side script then provides JSON encoded data for the plugin to update the table.
Compass Datagrid will work with any server-side programming language (the example in the download is in PHP). Compass DataGrid is released under the MIT and GPL license.
