title: struts2: s:checkbox doesn't go on the same row with s:checkbox
body: <p>Here's the .jsp code:</p>
  
  <pre><code>&lt;table&gt;
          &lt;s:iterator value="allAgents"&gt;
              &lt;tr&gt;
                  &lt;td&gt;&lt;s:property value="firstName" /&gt;&lt;/td&gt;
                  &lt;td&gt;&lt;s:property value="middleName" /&gt;&lt;/td&gt;
                  &lt;td&gt;&lt;s:property value="lastName" /&gt;&lt;/td&gt;
                  &lt;td&gt;&lt;s:checkbox name="ss"/&gt;&lt;/td&gt;
              &lt;/tr&gt;
          &lt;/s:iterator&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>When rendered, the checkbox would occupy a whole row below the 'names', centered.
  Here's the generated html for what's supposed to be a single row:</p>
  
  <pre><code>&lt;tr&gt;
      &lt;td&gt;first&lt;/td&gt;
      &lt;td&gt;middle&lt;/td&gt;
      &lt;td&gt;last&lt;/td&gt;
      &lt;td&gt;
  &lt;tr&gt;
      &lt;td valign="top" align="right"&gt;&lt;/td&gt;
      &lt;td valign="top" align="left"&gt;&lt;input type="checkbox" name="ss"
          value="true" id="agent_ss" /&gt; &lt;input type="hidden"
          name="__checkbox_ss" value="true" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  
  &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>Is it me or struts?
  TIA.</p>
