xp:viewPanel - Leading and closing empty table row - xpages

Question

I have the following simple xpage with a xp:viewPanel :
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:viewPanel rows="30" id="viewPanel1" disableTheme="true">
<xp:this.data>
<xp:dominoView var="view1" viewName="testView"></xp:dominoView>
</xp:this.data>
<xp:viewColumn columnName="$0" id="viewColumn1">
<xp:viewColumnHeader value="Col 1" id="viewColumnHeader1"></xp:viewColumnHeader>
</xp:viewColumn>
</xp:viewPanel>
</xp:view>
Although pagers are disabled for header and footer, the generated HTML has always a leading an closing empty row around the view data:
<table id="view:_id1:viewPanel1_OUTER_TABLE" cellspacing="0" cellpadding="0">
<tr>
<td> </td><td> </td><td> </td>
</tr>
<tr>
<td colspan="3" style="padding:0px" width="100%" height="100%" valign="top">
<table id="view:_id1:viewPanel1">
<thead>
<tr>
<th scope="col">
<div><span><span id="view:_id1:viewPanel1:viewColumn1:__internal_header_title_id">Col 1</span></span></div>
</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<span id="view:_id1:viewPanel1:0:viewColumn1:_internalViewText"> </span>
</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td> </td><td> </td><td> </td>
</tr>
</table>
What can I do to hide/ delete this empty rows?
I already added an empty theme and used it in the test database, but that did not help:
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="platform:/plugin/com.ibm.designer.domino.stylekits/schema/stylekit.xsd">
</theme>
I am using Domino Domino 8.5.3 Upgrade Pack 1
Thx in advance

Edit 04/24/2012 :
Thanks to Ulrich Krause, his answer gave me the right direction and I ended up in writing my own theme extension.
<theme extends="webstandard" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="platform:/plugin/com.ibm.designer.domino.stylekits/schema/stylekit.xsd">
<!-- ================== View Table with no footer and header ================================ -->
<!-- View DataTable - copied from webstandard theme and customized (Notes\xsp\nsf\themes)-->
<control >
<name>DataTable.ViewPanelNoHeaderFooter</name>
<property>
<name>headerEndStyle</name>
<value>display: none;</value>
</property>
<property>
<name>headerStartStyle</name>
<value>display: none;</value>
</property>
<property>
<name>headerStyle</name>
<value>display: none;</value>
</property>
<property>
<name>footerStyle</name>
<value>display: none;</value>
</property>
<property>
<name>footerStartStyle</name>
<value>display: none;</value>
</property>
<property>
<name>footerEndStyle</name>
<value>display: none;</value>
</property>
</control>
</theme>
With that theme extension i can set the theme id for my xp:viewPanel to "DataTable.ViewPanelNoHeaderFooter" where needed and the header and footer row are hidden.
<xp:viewPanel rows="30" id="viewPanel1"
themeId="DataTable.ViewPanelNoHeaderFooter">
<xp:this.data>
<xp:dominoView var="view1" viewName="testView"></xp:dominoView>
</xp:this.data>
<xp:viewColumn columnName="$0" id="viewColumn1">
<xp:viewColumnHeader value="Col 1" id="viewColumnHeader1">
</xp:viewColumnHeader>
</xp:viewColumn>
</xp:viewPanel>

Answer 1

I'm using a theme for this. It sets the empty .xspDataTableViewPanelHeaderStart etc to display:none.
Inspect with firebug to find the elements. Would post solution, but only have a smartphone at the moment.

Answer 2

Try using disableTheme="true" as a property of the pager and see if that gets rid of the code.
<xp:pager partialRefresh="true" layout="Previous Group Next"
xp:key="headerPager" id="pager1" disableTheme="true">
</xp:pager>
