row's height

[Matteo Regazzo <matteo.regazzo@cmz.it>]

Hi everybody,

I have a question that I hope is simple for many expert users (of 
course, I'm a beginner...)
I have a table with 2 columns:
- in the tbody of the first column there are 3 rows,
- in the tbody of the second column there is a figure that takes the 
entire place of the three rows;

in this way:


<informaltable>
   <tgroup cols="3">
     <colspec colname="c1" colwidth="15*"/>
     <colspec colname="c2" colwidth="70*"/>
     <thead>
        <row>
           <entry align="center"><para>PIN</para></entry>
           <entry align="center"><para>Scheme</para></entry>
         </row>
     </thead>
     <tbody>
         <row>
            <entry align="center"><para>1</para></entry>
            <entry align="center" morerows="2" 
valign="middle"><para><informalfigure>
                 <mediaobject>
                   <imageobject role="fo">
                     <imagedata align="center" 
fileref="figure/Table_BrakeResistor.svg" scale="70"/>
                   </imageobject>
</mediaobject></informalfigure></para>
            </entry>
          </row>
          <row>
             <entry align="center"><para>2</para></entry>
          </row>
          <row>
              <entry align="center"><para>3</para></entry>
          </row>
       </tbody>
    </tgroup>
</informaltable>


The problem is that the picture's height is greater than the total 
height of the 3 rows.
I've not found any property of the table, row, colspec, entry, or other 
elements that can help me to define the height of the columns or that 
can set an auto-resize of the row's height to be equals.

Can you help me?

thank you since now,
Matteo
