DataTables AJAX source example - null data source for a column

Preamble

In some tables it can be useful to not need to specify any data source for a column, as it's content is automatically generated (for example using fnRender). This is fairly common with add, edit and delete columns for a CRUD interface. You can now use the mData set to null to specify that the column has no data source. DataTables will render this column as empty.

			null,
			null,
			null,

			{ "mData": null }
		]
	} );
} );
