Use tr:first-child to take the first tr:
.category_table tr:first-child td { vertical-align: top; }
If you have nested tables, and you don't want to apply styles to the inner rows, add some child selectors so only the top-level tds in the first top-level tr get the styles:
.category_table > tbody > tr:first-child > td { vertical-align: top; }
