[PHP-DOC] Problem with tables

[Anthony Bedford]

Hi,

In my DocBook source I have something like:
  <informaltable>
    <tgroup cols="4">
      <colspec colwidth="10*"/>
      <colspec colwidth="15*"/>
      <colspec colwidth="40*"/>
      <colspec colwidth="35*"/>
      <thead>
        <row>
          <entry>Statistic</entry>
          <entry>Scope</entry>
          <entry>Description</entry>
          <entry>Notes</entry>
        </row>
      </thead>
      <tbody>
        .....
      </tbody>
    </tgroup>
  </informaltable>

However, the generated HTML is:

<table class="doctable informaltable">
<col width="250%" />
<col width="375%" />
<col width="1000%" />
<col width="875%" />
...

Note the interesting values for col width. I get the same values  
regardless of what I set colspec to, and can even comment colspec out  
and I will still get the same col width values.

Am I doing something wrong here (I'm having a Muddled Monday)?

Thanks,
Tony
