I'm not too sure what you're after. A table's width can be set to maximum as you have already done with width=100%, but the height of the overall table and the rows within it will be dictated by the content of the table cells. In web pages height in general is much harder to control than width, particularly with table based layouts.

The page at http://en.pijaja.com/Default.aspx?alias=en.pijaja.com/test-pijaja looks OK to me - can you explain a bit more what you're trying to achieve.

A picture is worth a thousand words . I now understand what you are trying to do, but I think my ability to help may have run out .

What you are seeing is the table being laid out 'properly' - this is how a table should appear. What you want goes beyond what tables were intended for. It's a long shot, and bound to have problems cross-browser, but you could try style="height=100%;" on the MiddlePane TD. Assuming this doesn't work, you'll have to move into nested tables, something like this;

<table border="0" bgcolor="green" cellpadding="0" cellspacing="0" style="width: 100%;">
   <tr>
      <td id="TopPane" class="toppane" colspan="2">Top Pane</td>
   </tr>
   <tr>
      <td valign="top" id="LeftPane" class="leftpane">Left Pane<br>
      Left Pane<br>
      Left Pane<br>
      Left Pane<br>
      Left Pane<br>
      Left Pane<br>
      Left Pane<br>
      </td>
      <td valign="top">
      <div id="ContentPane" class="contentpane">
         Content Pane</div>
      <table border="0" bgcolor="red" cellpadding="0" cellspacing="0" style="width: 100%;">
         <tr>
            <td valign="top" id="MiddlePane" class="middlepane">Middle Pane<br>
            Middle Pane<br>
            Middle Pane<br>
            </td>
            <td valign="top" id="RightPane" class="rightpane">Right Pane<br>
            Right Pane</td>
         </tr>
      </table>
      </td>
   </tr>
   <tr>
      <td id="BottomPane" class="bottompane" colspan="2">Bottom Pane</td>
   </tr>
</table>

Nested tables is widely regarded as being a bad way to do things these days. If you can't get what you want working I would consider looking at XHTML + CSS layouts. It's harder to get started, but once you have a good layout debugged and working it's much easier to maintain and is more likely to produce consistent results cross browser.
