Your code is a bit confused...

  You have a nested "dtml-in": "sequence-item" refers to the innermost
  "dtml-in", i.e. "DbQuery1".
  Therefore, "_.getitem('sequence-item')" is one row of your
  result, an "r instance", as you can see.

I would do it like this (avoidung the Python Script and the
second query execution):

     <dtml-let result__=DbQuery1
               names__="result__.names()">
	<dtml-in result__ size=20 start=query_start>
	  <dtml-if sequence-start>
	    <table>
	    <tr><dtml-in names__><th>&dtml-sequence-item;</th></dtml-in></tr>
	  </dtml-if>
	    <tr><dtml-in names__><td><dtml-var "_['sequence-item']" html_quote></td></dtml-in</tr>
	  <dtml-if sequence-end>
	    </table>
	  </dtml-if>
	</dtml-in>
    </dtml-let>
