I have a problem ... I do not understand why the buttons do not appear in the view :(
<h:body>
<h:form id="frmPrincipal">
<p:dataTable>
<p:column headerText="Boton1">
<p:commandButton value="1"/>
</p:column>
<p:column headerText="Boton2">
<p:commandButton value="2"/>
</p:column>
</p:dataTable>
</h:form>
</h:body>
