Table width with i*

I think this is a bug:

code:

---------------------------------------

<table width="100%">

<colgroup span="1" width="1*"></colgroup>
<colgroup span="2" width="1*"></colgroup>

<thead>
    <tr>
        <th>title 1</th>
        <th>title 2</th>
        <th>title 3</th>
    </tr>
</thead>

<tbody>
</tbody>

</table>

-----------------------------------------

just type it into Amaya, it shows not normal as HTML 4.01 Specification.
