Table tbody scroll in IE8

I found two ways to solve this problem in IE8.

       1)   Adding extra td element of width: 0px to tr‘s of thead and tbody.

       2)   Adding a hidden letter to content of after pseudo selector.

    tr:after{
        content: ".";
        visibility: hidden;
    }

I added the above in conditional css. because the problem was only in IE8. (I haven’t tested in IE9+)

    <!--[if IE 8]>
         <style>
             /* the above css code here */
         </style>
    <![endif]-->

I used the latter one because it is simple.
