table-layout: fixed in Internet Explorer breaks large tables

I seem to have stumbled upon a bug (or at least I think so). The bug occurs in Internet Explorer 7 and Internet Explorer 8 in "compatible mode".

Here is a test-page which reproduces the bug:

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>

<style type="text/css">

table { width: 900px; table-layout: fixed; }

.gray th, .gray td { background-color: #c2c2c2; }

.width200 { width: 200px; }

.width50 { width: 50px; }

</style>
</head>

<body>
<form runat="server">
<table cellpadding="0" cellspacing="0">
<thead>
<tr> <!-- When using "table-layout: fixed" the first row
serves as a guide to the width of the following
columns -->
<th class="width200"></th>
<th class="width200"></th>
<th class="width200"></th>
<td></td>
<td class="width50"></td>
<td class="width50"></td>
</tr>

<tr>
<th>---</th>
<th>---</th>
<th>---</th>
<td>///</td>
<td>///</td>
<td>///</td>
</tr>
</thead>

<tbody>
<% for (var i = 0; i <= 5000; i++) { %>
<tr class="gray">
<th>---</th>
<th>---</th>
<th>---</th>
<td>///</td>
<td>///</td>
<td>///</td>
</tr>
<% } %>
</tbody>

<tfoot>
<tr>
<th>---</th>
<th>---</th>
<th>---</th>
<td>///</td>
<td>///</td>
<td>///</td>
</tr>
</tfoot>
</table>
</form>
</body>
</html>





Here's a screenshot of what happens:



Is there any way to fix this?

Answer

I'm a bit concerned about the semantics of your markup, and wonder if that is what is causing your problem (default stylesheet not overridden). Why is there any td tags in the table head? and why are there th tags in the body and foot of the table? According to the [w3c reccomendation][1]:

TH is for headers, TD for data, but for cells acting as both use TD

The foot should also be before the body (this may be the main cause).
