title: Primefaces facet header button
body: <p>I have a datatable in Primefaces:</p>
  
  <pre><code>    &lt;p:dataTable var="feedback" value="#{actionDetailsView.action.feedback}"&gt;
                  &lt;f:facet name="header"&gt;
                      Feedback
                  &lt;/f:facet&gt;
  
                  &lt;p:column headerText="Date"&gt;
                      ...
                  &lt;/p:column&gt;
  </code></pre>
  
  <p>Now I want to have a button (Add Feedback) inside the header on the right hand side. Is this somehow possible?</p>
