How to customize the "No entries match your request." text

If you'd like to customise the text "No entries match your request." when you DataTables table is empty, you could use the plugin hook gravityview/datatables/config/language as follows:

// Replace empty table label, default: "No entries match your request."
add_filter( 'gravityview/datatables/config/language', 'my_gv_datatables_labels', 10, 1 );
function my_gv_datatables_labels( $labels ) {
	$labels['emptyTable'] = 'My new label when there are no results.';
	return $labels;
}

Paste the code above in your theme's functions.php file.
