namespace Inc\admin;

class Admin {
        public static function get_vendors() {
        require_once PLUGIN_PATH . 'inc/admin/MV_Vendors.php';

        $tableData = new MV_Vendors();

        $tableData-prepare_items();

        return $tableData-display();
    }

    public function admin_page_mv_vendors() {
        $vendors = self::get_vendors();
        
        require_once( PLUGIN_PATH . 'inc/admin/pages/template-all-vendors.php');
    }
