according to our company's policy, I can't give all the project. 2 jade views affixed. the node server responses like:
res.render('data-table', { cols: cols, tableName: req.params.table, chart: req.params.table, show_date_search: show_date_search });

Till now, everything is ok, including table & charts, except this issue. thank you for helping me
