title: $table.floatThead() not recognized as a function
body: <p>I'm trying to froze the <code>thead</code> table on the top of the screen when scrolling the table by using the jquery <code>floatThead()</code> function. 
  I'm referencing the jquery to the page but it is not working when I press the f12 key there is an X saying "floatThead is not a function".
  this is the jquery code:</p>
  
  <pre><code>$(function () {
      var $table = $('table.tableTop');
      $table.floatThead();
  });
  </code></pre>
  
  <p>and this is the html:</p>
  
  <pre><code>&lt;table class="tableTop"&gt;
  &lt;thead&gt;
      &lt;tr&gt;
          &lt;th&gt;.....
  </code></pre>
  
  <p>this is the error:
