In many cases you would like not only to display the table values to the front-end users of your site, but also allow them to edit these values: e.g. displaying and managing orders, or managing issues in a bugtracker, or whatever you can think of else.
wpDataTables allows both front-end and back-end editing.
Also it is possible to allow front-end users to edit only their own data.
This section contains videos that explain all the features related to editable wpDataTables.
