DataTables is a plug-in for the jQuery Javascript library. It is a highly flexible tool, based upon the foundations of progressive enhancement, and will add advanced interaction controls to any HTML table. For more info see the official site.

Sub Datatable Example

This example shows the DataTables table with an expandable row. The sub-rows data are generated by using DataTable's template methods with simple JS data objects that can either be generated locally or retrieved from an API endpoint.
