<dvt:pivotTable> Highlight columns with background color

@Timo Hahn :The mark in the image is on a row. -Sorry for the confusion, that's some other requirement

you can see the column (weekend, holiday) highlighted in orange color - that's the requirement.

Code for the pivot table:

 <dvt:pivotTable id="pt1" value="#{bindings.MeldungPersonROVO.pivotTableModel}" var="cellData"

                  varStatus="cellStatus" splitMode="enabled" pivotEnabled="false"

                  preferredColumnHeaderHeight="100" preferredRowHeaderWidth="100"

                  sizing="#{bindings.MeldungPersonROVO.estimatedRowCount>0?'auto':'fixed'}"

                  summary="Meldung Person" columnFetchSize="10" contentDelivery="immediate"

                  sortMode="none" inlineStyle="margin-top: 5px;margin-bottom: 5px;"

                  layerLabelMode="rendered" >

            <dvt:headerCell>

              <af:switcher facetName="#{cellData.layerName}" defaultFacet="Default" id="s2">

                <f:facet name="DataLayer">

                  <af:outputText value="#{cellData.label}"  id="ot1"/>

                </f:facet>

                <f:facet name="Tag">

                  <af:outputText value="#{cellData.dataValue}" id="ot2"

                  />

                </f:facet>

                <f:facet name="Mitarbeiter">

                  <af:outputText value="#{cellData.dataValue}" id="ot3"/>

                </f:facet>

                <f:facet name="Default">

                  <af:outputText value="#{cellData.dataValue}" id="ot4"/>

                </f:facet>

              </af:switcher>

            </dvt:headerCell>

            <dvt:dataCell id="dc1">

              <af:switcher facetName="#{cellStatus.members.DataLayer.value}" defaultFacet="Default"

                     id="s4">

                <f:facet name="GrundAbbr">                 

                  <af:outputText value="#{cellData.dataValue}"  id="o86" 

                          rendered="#{not empty cellData.dataValue}"/>

                </f:facet>

                <f:facet name="Default">

                        <af:outputText value="" id="ot10" shortDesc="#{cellData.dataValue}"

                          rendered="#{not empty cellData.dataValue}"/>

                </f:facet>

              </af:switcher>

            </dvt:dataCell>

          </dvt:pivotTable>

@Timo Hahn After adding headerFormat and dataFormat I was able to highlight weekends(header data) as below.

But my requirement is to highlight every cell below and above "SA" and "SO "as posted in the earlier image.
