I fully agree with your opinion, but my client want the vertical borders…
I may talk with him about this. Otherwise, I may have to find out how to switch <tbody> and <thead> because when I swap them manually on the browser’s built-in inspect tool, the disappeared border shown up.
Anyway thanks very much to give me fast, long feedback!

Thanks for fast answer for my question. I added css for making border lines
border: 1px solid #C6C6C6 !important;
on the table but this does not work on Chrome. (Works on Firefox and IE) So I inspect the webpage, it says that the table’s thead tag and tbody tag are swapped. You know, thead tag have to be prior to tbody tag, but it was reversed so that border css does not work if I enable FixedHeader.

Before full load, This is what the table have to be shown.

After full load, border lines in the table are disappeared.
(Border lines have to be remained there)
