http://jsbin.com/lebokewi/1/edit?html,css,output

css

table, th, tr, td {   border: 1px solid #000; }  #colhdr th:nth-of-type(1) {width: 100px;} #colhdr th:nth-of-type(2) {width: 50px;} #colhdr th:nth-of-type(3) {width: 200px;} #colhdr th:nth-of-type(4) {width: 60px;} #colhdr th:nth-of-type(5) {width: 80px;}

example

<table>     <col width="130">     <col width="80">     <tr>         <th>month</th>         <th>savings</th>     </tr>     <tr>         <td>january</td>         <td>$100</td>     </tr>     <tr>         <td>february</td>         <td>$80</td>     </tr> </table>
