                            $pdocrud = new PDOCrud();
                            $pdocrud->crudTableCol(array("first_name","last_name","user_name","gender"));
                            $pdocrud->joinTable("user_meta", "users.user_id = user_meta.user_id", "LEFT JOIN");
                            echo $pdocrud->dbTable("users")->render();
