How to remove spaces between cells in a html table

I try to remove white space between Table1Header and Table2Header. I tried border:0px, padding:0px and border-spacing:0px; styles. Firefox and Opera tell me that my border-spacing style is overrided by the user agent style (which is 2px). How can I force browser to use my styleshits?

<table class="tableGroup">
<tbody>
<tr>
<td>
<table>
<tbody>
<tr class="tableHeader">
<td><span class="tableHeader"><label>Table1Header</label></span>

</td>
</tr>
<tr class=" tableData">
<td>
<div class="ui-datatable">
<div>
<table>
<thead>
<tr>
<th>
<div><span><span class="ui-header-text">Table1Col1</span></span>
</div>
</th>
</tr>
</thead>
<tbody>
<tr>
<td><span>2</span>

</td>
</tr>
</tbody>
</table>
</div>
</div>
</td>
</tr>
</tbody>
</table>
</td>
<td>
<table>
<tbody>
<tr class="tableHeader">
<td><span class="tableHeader"><label>Table2Header</label></span>

</td>
</tr>
<tr class="tableData">
<td>
<div class="ui-datatable">
<div>
<table>
<thead>
<tr>
<th>
<div><span><span class="ui-header-text" >Table2Col1</span></span>
</div>
</th>
</tr>
</thead>
<tbody>
<tr>
<td><span>12345</span>

</td>
</tr>
</tbody>
</table>
</div>
</div>
</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>

span.tableHeader > label {
display: inline-block;
float:left;
line-height:30px;
padding-left:10px;
color: #202020;
font-size: 13px;
}
tr.tableHeader {
background-color: #EEEEEE;
}
table.tableGroup, table.tableGroup > tr > td > table {
border-spacing: 0px;
}
table.tableGroup div.ui-datatable th > div > span >span.ui-header-text {
color: #808080;
font-size: 11px;
}
table.tableGroup td, table.tableGroup th {
padding: 0px;
border: 0px;
}
