Af:treeTable: how build tree that displays multiple columns?

Question

I only find a default single column behavior in the dev guide regarding af:treetable. Perhaps some of you might have already tried this out, I'm trying to build a master detail using a treetable with multiple columns. After establishing the ViewLink association and dragging the Master View Object onto the cavas, the default generated code looks like:
<af:treeTable ...
<f:facet name="nodeStamp">
<af:column binding="#{backing_tree.column1}" id="column1"
sortable="false" headerText="">
<af:outputText value="#{node}"
binding="#{backing_tree.outputText1}"
id="outputText1"/>
</af:column>
</f:facet>
</af:treeTable>
This renderes the entire tree in one column, but my detail ViewObject contains multiple attributes and I would like seperate columns to display those values. I'm not sure how to extract the "#{node}" EL to output the detail or child ViewObject's values in seperate af:column. Can someone advise? Thank you.

Luis, thanks for the suggestion. I did get the header labels to show, however, the values are still not being printed correctly. I have department as the Master or parent node and employee as the Detail or child node. Here is what I have
<af:treeTable value="#{bindings.DeptView1.treeModel}" var="node"
binding="#{backing_treeTest.treeTable1}" id="treeTable1"
rowsByDepth="0 0">
<f:facet name="nodeStamp">
<af:column binding="#{backing_treeTest.column1}" id="column1">
<f:facet name="header">
<af:outputText value="Department Name"/>
</f:facet>
<af:outputText value="#{node.Dname}"
binding="#{backing_treeTest.outputText1}"
id="outputText1"/>
</af:column>
</f:facet>
<f:facet name="pathStamp">
<af:outputText value="#{node.Dname}"
binding="#{backing_treeTest.outputText2}"
id="outputText2"/>
</f:facet>
<af:column>
<f:facet name="header">
<af:outputText value="Employee Name"/>
</f:facet>
<af:outputText value="#{node.Ename}"
binding="#{backing_treeTest.outputText3}"
id="outputText3"/>
</af:column>
</af:treeTable>
The Tree Table looks Like:
Department Name | Employee Name
- Accounting
Thanks in advance,
