title: dynamically add rows to jquery treetable *not at root*
body: <p>I'm using the treetable plugin and I want to dynamically load some rows of data from a Taffy db previously populated from an xml file. I've verified that loadBranch works fine on the root of the table using "null" as the node but I can't seem to make it child of the first row.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;table id='data_tree'&gt;
  &lt;tr class="branch" data-tt-id="1"&gt;
  &lt;td&gt;Studies&lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Javascript:</p>
  
  <pre><code>$(window).load(function(){
      studies_db().each( function (record,recordnumber) {
          $("#data_tree").treetable("loadBranch",1,
                              "&lt;tr&gt;"+
                              "&lt;td&gt;&lt;b&gt;Accession:&lt;/b&gt; "+record.accession+"&lt;br&gt;"+
                              "&lt;b&gt;Title:&lt;/b&gt; "+record.title+"&lt;br&gt;"+
                              "&lt;b&gt;Authors:&lt;/b&gt; "+record.authors+"&lt;br&gt;"+
                              "&lt;b&gt;Release date: &lt;/b&gt;"+record.date+"&lt;br&gt;"+
                              "&lt;b&gt;Number of markers: &lt;/b&gt;"+record.samples+"&lt;br&gt;"+
                              "&lt;/td&gt;&lt;/tr&gt;")
           });
  });
  </code></pre>
