I use 'dataTables - plug-in' in my project.

I use 'colgroup' for td width.

but, The certain td has too long text. So, It makes the problem. th width , td width are different.

How can I manage td width, th width ?

Oh. if there is a scroll-bar option, there are two tables in dataTables.

One is for th. Another is for tbody.

I tested in url 'https://datatables.net/examples/basic_init/scroll_xy.html'.
