The treeTable component visualizes tree where each tree item can have some additional fields that could be displayed in a tabular format.
A basic implementation for treeTable with three columns would be as follows:
<p:treeTable id="simple" value="#{treeTableBean.root}"
var="element">
<f:facet name="header">Tree Table</f:facet>
<p:column>
<f:facet name="header">Name</f:facet>
<h:outputText value="#{element.name}" />
</p:column>
<p:column>
<f:facet name="header">Column 1</f:facet>
<h:outputText value="#{element.column1}" />
</p:column>
<p:column>
<f:facet name="header">Column 2</f:facet>
<h:outputText value="#{element.column2}" />
</p:column>
</p:treeTable>The visual output of the table expanded on every node will be as shown here:
The root element of the tree table will be an instance of org.primefaces...
