    <tr>
        <td><i>Overskrift</i></td>
        <td><i>Antal svar</i></td>
        <td><i>Sidste svar af</i></td>

    </tr>
<?php foreach ($activeQuery as $activeThread): ?>
    <tr>
        <td><a href="<?php echo base_url(); ?>forum/post/<?php echo $activeThread->traadID; ?>">
        <?php echo $activeThread->traadOverskrift; ?></td>
        <td><?php ?></td>
        <td><?php echo $activeThread->kommentareBrugernavn; ?></td>
        <td><abbr class="timeago" title="<?php echo $activeThread->kommentareDato; ?>">
        <?php echo $activeThread->kommentareDato; ?></abbr></td>
    </tr>
<?php endforeach ?>
</table>

Maybe the nth-child() selector is a better choice for this case

$("tr:nth-child(even)").css("backgroundColor", "#bbbbff");

You can use the :even and/or :odd selector

$("tr:gt(0):even td").css("background-color", "#bbbbff");

or

$("tr:gt(0):odd td").css("background-color", "#bbbbff");
