DataTable.isDataTable()
Check is a table node is a DataTable or not.
Description
This method provides the ability to check if a table node is already a DataTable or not. This can be useful to ensure that you don't re-initialise a table that is already a DataTable.
Please note that this is a static function and is accessed through the DataTable or $.fn.dataTable object, not an API instance. It can be accessed at any time, even before any DataTables have been created on the page.
Prior to DataTables 1.11 this method could be accessed through the $.fn.dataTable object only. As of 1.11, either DataTable or $.fn.dataTable can be used.
