Docbook <programlisting> alignment

Hi,
I have a <table> that has <programlisting> in one of the columns. Instead of
both the columns being left aligned, the <programlisting> column is
'centered' at page level because of which it overlaps the text in column2.

How can we programmitacally set the <programlisting> alignment so that it
does not do a centre alignment when enclosed in a table?

Following is a sample code:
           <table id="someid" label="1.1">
              <title>Sample table</title>
              <tgroup cols="2">
                 <colspec colnum="1" colname="col1"/>
                 <colspec colnum="2" colname="col2"/>
                 <thead>
                    <row>
                       <entry>
                          <para>Method</para>
                       </entry>
                       <entry>
                          <para>Description</para>
                       </entry>
                    </row>
                 </thead>
                 <tbody>
                    <row>
                       <entry>
                          <programlisting>
                             <emphasis>private void getMe()</emphasis>
                           </programlisting>
                        </entry>
                        <entry>
                           <para>gets me</para>
                        </entry>
                     </row>
                 </tbody>
              </tgroup>
           </table>


Thanks for your help in advance!
