Ok, the .parent() is wrong because I have to access the tableInner
inside tableOuter. The sourcecode of tableOuter is the following:
<table border="0">
<colgroup>
<col>
</colgroup>
<tbody>
<tr>
<td>
<div style="position: relative; overflow-x:
hidden; overflow-y:
hidden; ">
<button tabindex="0" type="button"
class="gwt-Button">add outer</
button>
</div>
</td>
</tr>
<tr>
<td>
<div style="position: relative; overflow-x:
hidden; overflow-y:
hidden; " class="divOuter">
<div class="gwt-HTML">
<h2>outer</h2>
</div>
<table border="0" class="divInner">
<colgroup>
<col>
</colgroup>
<tbody>
<tr>
<td>
<button
tabindex="0" type="button" class="gwt-Button">add
inner</button>
</td>
</tr>
</tbody>
</table>
</div>
</td>
</tr>
<tr>
<td>
<div style="position: relative; overflow-x:
hidden; overflow-y:
hidden; ">
<button tabindex="0" type="button"
class="gwt-Button">add outer</
button>
</div>
</td>
</tr>
</tbody>
</table>
, but how can I access the inner table in the first column of the
second row which has the class="divInner" attribute?
