<rich:column sortBy="#{satir.kod}" sortMode="multiple">
<f:facet name="header"><h:outputText value="Kod" /></f:facet>
<h:commandLink action="#{Tanim.araKod}" styleClass="comlink" >
<h:outputText value="#{satir.kod}" id="out" styleClass="cell" ></h:outputText>
</h:commandLink>
</rich:column>
<rich:column sortBy="#{satir.grup}" sortMode="multiple">
<f:facet name="header"><h:outputText value="Grup"></h:outputText> </f:facet>
<h:commandLink action="#{Tanim.araKod}" styleClass="comlink" >
