<parameter type="string|node|jQuery|DataTable.Api" name="version">
The table to check. This can be given as one of:
* A DOM element
* A jQuery selector
* A jQuery object containing the node to check
* A DataTables API instance.
Note that only the first node is checked if the jQuery selector or object match multiple nodes.

<description>
This method provides the ability to check if a `-tag 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 `$.fn.dataTable` object, not an API instance. It can be accessed at any time, even before any DataTables have been created on the page.

if ( ! $.fn.DataTable.isDataTable( '#example' ) ) {
$('#example').dataTable();
}
]]></example>
