I have a html table which is as follows
<table class="report">
<tbody>
<tr>
<td >col1</td>
<td >col2</td>
<td>col3</td>
<td > </td>
<td > </td>
<td > </td>
<td > </td>
</tr>
<tr>
<td>R2</td>
<td >2/17</td>
<td >{2/17}</td>
<td > </td>
<td > </td>
<td > </td>
<td > </td>
</tr>
</tbody>
</table>
as you can see , after col3 , all subsequent columns are empty. I want to show only first three columns and hide the rest. How can i achieve this using CSS. I dont have control over HTML table so i can not modify it.
Thanks
