Primefaces datatable, item on multiple rows - jsf-2

Question

I can not find a primefaces datatable example on how to make one item to be shown on two (or more) rows.
I need to show an item in a datatable about like this:
<table>
<tr>
<td>Text 1 from entry</td>
<td>Text 2 from entry</td>
</tr>
<tr>
<td colspan="2">Text 3 from entry</td>
</tr>
</table>
Can it be done or should I use some other tag to render like this?
I tried:
...xmlns:p="http://primefaces.org/ui"...
<p:dataTable var="item" value="#{bean.items}">
<p:column>
<p:row>
<p:column>
<h:outputText value="#{item.title}" />
</p:column>
<p:column>
<h:outputText value="#{item.shortText}" />
</p:column>
</p:row>
<p:row>
<p:column colspan="2">
<h:outputText value="#{item.longText}" />
</p:column>
</p:row>
</p:column>
</p:dataTable>
But obviously this is wrong and/or I have misunderstood the concept of using 'p:row'. I can not find any explanation on how to do this properly, so any advice would be appreciated.

Answer 1

Why don't you want to use the <p:panelGrid> component that can achieve this functionality easily?
Basic example:
<p:panelGrid>
<p:row>
<p:column>Text 1 from entry</p:column>
<p:column>Text 2 from entry</p:column>
</p:row>
<p:row>
<p:column colspan="2">Text 3 from entry</p:column>
</p:row>
</p:panelGrid>
That embedded, we have:
<p:dataTable var="item" value="#{bean.items}">
<p:column>
<p:panelGrid>
<p:row>
<p:column><h:outputText value="#{item.title}" /></p:column>
<p:column><h:outputText value="#{item.shortText}" /></p:column>
</p:row>
<p:row>
<p:column colspan="2"><h:outputText value="#{item.longText}" /></p:column>
</p:row>
</p:panelGrid>
</p:column>
</p:dataTable>
