Custom Cell in DataTable

Question

Hi Guys,
need you for a little question, I have a dataTable and dynamic columns:
<rich:dataTable var="item" value="#{class.method}"
                      styleClass="reportTable">
        <h:column>
          <f:facet name="header">
            <h:outputText value="xx" styleClass="firstCellContent"/>
          </f:facet>
          <h:outputText value="#{item.getLastName()}" styleClass="firstCellContent"/>
        </h:column>
        <c:forEach var="yy" items="#{class.getYY()}">
          <h:column>
            <f:facet name="header">
              <h:outputText value="#{yy}"/>
            </f:facet>
            <h:outputText value="#{item.getFoo(yy)}" />
          </h:column>
        </c:forEach>
      </rich:dataTable>getFoo return a value between 0 and 100.
I need to apply different styleClass for number from 0 to 20, 21 to .... etc
I can for sure doing it with rendered..
but I want to do it properly in the Java code.... What is the best ?
I tried some binding tricks but without expecting results, I couldnt get the dynamic Cell Value
Thx

That code snippet won't even run.
Anyway, regarding to your actual question: you can just use EL in the styleClass attribute. Either write a conditional expression which takes the value in evaluation, or write a new method in the row object which returns the right styleClass value.
