To install the DataTables extension, download it from your Account page, install it on your site as an extension, and activate it.
If you have an existing View configured where you would like to use the DataTables extension, edit the View, click the "Switch View Type" button, and select the "DataTables Table" option.
If you don't have a View configured, create a new View, select an existing form to integrate with, and choose the DataTables View Type option.
When you select the DataTables option, you will see a new "DataTables Settings" box appear beneath the "View Settings" box. You can then enable or disable some DataTables Extensions included in GravityView.
