Hi, @Dongsup Lee
I also have the same case (maybe), I solved in 2 ways.
1. I made custom Tab Widget (I only use hide and show container)
2. I using tab widget, but in Tabs Widget property (OnTabChange), I use Refresh Ajax into each table that I need.
In my Case, both method work well.
I attach oml file, and I hope this things can help your case.
