Calling css classes

Question

Hi..

I have the following in my "MyDesigns.css" file -

.table{Border="2"}.table th,
.table td{padding:8px;}
.table th{font-weight:bold;}

How to call this in GridView controls ??

Here, the class ".table th" is used with ".table".

If I want to call this in GridView HeaderStyle CSS Class, how do I call ??
