i need to display the all products information under one category at a time.
The datatable should be column wise and completely dynamic
if i am going to display the car category i have two list for display the dataTable
one from Table_products and another one from Table_Car

this is my view part

<rich:dataTable var="product" value="#{table_products_list}">
 <f:facet name="header">
 <rich:columnGroup>
 <rich:column>
 <h:outputText value="property" />
 </rich:column>
 <c:forEach items="#{car_list}" var="car">
 <rich:column>
 <h:panelGroup>
 <h:outputText value="#{car .id}"/>  
 <h:commandLink value="Remove" action="#{bean.removeColumn}" /> </h:panelGroup>
 </rich:column>
 </c:forEach>
 </rich:columnGroup>
 </f:facet>
 <rich:column>
 <h:outputText value="#{product.property}" />
 </rich:column>

 <c:forEach items="#{car_list}" var="car">
 <rich:column>

 <h:outputText value="#{car.returnValue(product.property)}"/>

 </rich:column>
 </c:forEach>
</rich:dataTable>

try something like this

<c:forEach items="#{car_list}" var="car">
 <rich:column rendered="#{car.rendered}">
 <h:panelGroup>
 <h:outputText value="#{car .id}"/>

<h:commandLink value="Remove" action="#{bean.removeColumn}" />
 </h:panelGroup>
 </rich:column>
 </c:forEach>

even thou I am not so sure that datatable is designet for this kind of work. Datatable shows properties of same type (ex. Car (id,type,motor))
