Я хочу нажать на кнопку ниже, но не могу ее щелкнуть.

HTML это:

<table onclick="filtersJob_intrinsic_extender.addRow();return false;" class="FilterList_addLink">
<tbody>
<tr>
<td class="icon"><img src="/commander/lib/images/icn12px_add.gif" alt="Add Filter"></td>
<td class="text">Add Intrinsic Filter</td>
</tr>
</tbody>
</table>

Я делаю это в основном с помощью watir и watir-webdriver:

browser.td(:text => 'Add Intrinsic Filter').click

Я попробовал этот метод на другой аналогичной кнопке на другом сайте, и это сработало. Интересно, почему это не работает здесь.

Это вызывает исключение:
