i have a HTML table that looks somewhat like this

```
<tr rel="price">
    <th>Price</th>
    <td class="">-</td>
    <td class="">-</td>
    <td class="">-</td>
    <td class="">-</td>
</tr>

```

how would i insert data the the 4th td? I could give the 4th td an ID and insert like this

```
$('#id').html('bla bla');

```

but my table has 60 rows and 4 columns. Personally think it would be abit messy if i was going to add ID's to all td's. Any suggestions? Obviously something that works fast on a big table would be ideal. Thanks
