Ok, thank you: But do I do this in detail?
Assume I have the following HTML structure:
<body ...>
<table ...>
<tbody ....>
<tr>
<td width=NOT320px ....>
<td width=320px ...>
<td width=NOT320px ...>
</tr>
</tbody>
</table>
<table ...>
<tbody ....>
<tr>
<td width=NOT320px ....>
<td width=320px ...>
<td width=NOT320px ...>
</tr>
</tbody>
</table>
...
</body>
How do I change every second <td> width in a table?
