title: DisplayGroup decorator in Zend Framework
body: <p>I'm using DisplayGroup to render a couple of elements in a group. Now what I want to do, is render this group in a single table row. But it turns out, that Decorators on DisplayGroups do <strong>NOT</strong> work the same way they do on simple elements. An example:</p>
  
  <pre><code> $content = $this-&gt;getDisplayGroup('group');
   $content-&gt;setDecorators(array(
        'FormElements',
         array('HtmlTag', array('tag' =&gt; 'table', 'class' =&gt; 'element')),
          ));
  </code></pre>
  
  <p>This just puts
  <code>&lt;table&gt;&lt;/table&gt;</code> at the end of my DisplayGroup. I've also tried to alias them:</p>
  
  <pre><code>array(array('elementDiv' =&gt; 'HtmlTag'), array('tag' =&gt; 'table')),
  'FormElements',
  array(array('td' =&gt; 'HtmlTag'), array('tag' =&gt; 'table')),
  </code></pre>
  
  <p>Still puts them in one place, not both tried <code>openOnly</code> and <code>closeOnly</code> :</p>
  
  <pre><code>array(array('elementDiv' =&gt; 'HtmlTag'), array('tag' =&gt; 'table','openOnly'=&gt;true)),
  'FormElements',
  array(array('td' =&gt; 'HtmlTag'), array('tag' =&gt; 'table','closeOnly'=&gt;true)),
  </code></pre>
  
  <p>And it still puts in only the closing tag. If I change these to <code>&lt;td&gt;</code>, everything works fine, but not with <code>&lt;table&gt;</code> Am I missing something?</p>
