There is a issue not showing on table. If I change the { data: "ministry", render: "[, ].ministryname" } to { data: "ministry", render: "[, ].id" }, I can see the id value. But I use ministryname that can not show the value of ministryname.

the follow link is my website: http://member.bolkh.org.tw/system/group/member.php
