Hello , i am using datatable package and wanted to know how to pass footer array explicitly or just let it take last row as footer , i am fine with both: This is the code right now:

\koolreport\datagrid\DataTables::create(array(
            "themeBase"=>"bs4",
            "dataSource"=>$table_array,

            'cssClass'=>array(
                'th' => 'reportHeader',

            ),
            "options"=>array(
                "showFooter"=>true,
                "order" => [],

            )
        ));
