Slick Ajaxed Datagrids With jQuery – jTable
jTable is a jQuery plugin for creating Ajaxed and feature-rich CRUD interfaces with little effort.
The plugin generates all the HTML required and uses jQuery UI for "add new/edit record" dialogs.
Records can be browsed with Ajaxed pagination and they can be sorted (server-side) as well.
jTable can be set to display sub-tables for a given record which is handy for listing any sub-details.
The interface is completely themable via CSS (there are already several themes) and the resource is very well-documented.
P.S. There are samples provided on using jTable with PHP and ASP.NET
