Help! Tables

Hello,

I'm trying to format my tables (mainly for PDF output appearance, but a general look nonetheless).

Here is what I would like:

______________________
Column1   Column 2_____

           1   Some text here
           2   Some text here
         ...    ...
______________________

The basic idea is that numbers would be right aligned and text would be left. The size of the table is determined by the longest row.

I've tried making the tables with HTML and CALS, but my results are not satisfactory.  With HTML tables I get the size right, but no text alignment.  With CALS tables I can control the border appearance, but not the row separation, and the text does not align correctly.

Here is my code:

WITH CALS
<informaltable rules="rows"> 
       <tgroup cols='2'>
            <colspec colnum='1' colname='col1' colwidth='1*' align='right'/>

            <colspec colnum='2' colname='col2' colwidth='4*'/>
        <thead rowsep='1'>
          <row>
            <entry align='left'>type</entry>

            <entry>comments</entry>
          </row>
          </thead>
          <tbody>
          <row>
            <entry align='right'>0</entry>

            <entry>small group of binning settings</entry>
          </row>
          <row>
            <entry>1</entry>
            <entry>range of binning settings starting from 1</entry>

          </row>
        </tbody>
        </tgroup>
</informaltable>

WITH HTML
<informaltable>
    <colgroup>
        <col align="right"/>
        <col/>

    </colgroup>
    <thead>
          <tr>
            <th align="left">type</th>
            <th>comments</th>         
          </tr>
     </thead>

      <tbody>
          <tr>
            <td>0</td>
            <td>small group of binning settings</td>          
          </tr>
          <tr>
            <td>1</td>

            <td>range of binning settings starting from 1</td>            
          </tr>
      </tbody>
 </informaltable>

I use docbook-xsl-1.74.0, SAXON, XEP.  I've tried to do some tweeking with customizations, but I can't seem to get anything to work.  Thanks for any help!
