I have a table with white-space set to nowrap and columns widths restricted using table-layout fixed. This correctly hides long lines in Firefox, but in IE9 the lines are wrapping.
Test case:
<table border="1" width=200 style="white-space: nowrap; table-layout: fixed;">
<tr>
<td style="overflow: hidden;" width=150>Word with some spaces that isnt working in IE</td>
<td width=50>100/50</td>
</tr>
<tr>
<td style="overflow: hidden;" width=150>LoooooooooOOOOOOOOOoooooooooooooooooongword</td>
<td width=50>550/50</td>
</tr>
<tr>
<td style="overflow: hidden;" width=150>AnotherLoooooooooooonnnnnnnnnnnnnnnnGWord</td>
<td width=50>660/50</td>
</tr>
</table>

IE 9:
