 This repository contains a collection of plug-ins for the jQuery [DataTables](http://datatables.net) table enhancer. These plug-ins are feature enhancing for the DataTables library, adding extra options to core functionality such as additional sort algorithms, API methods and pagination controls. The plug-ins should not be confused with DataTables "extras" which are more significant software libraries which add additional features to DataTables.
