You should use the <p:columns , take a look at the showcase DataTable - Dynamic Columns

here a code snippet from the showcase

<p:dataTable id="cars" var="car" value="#{tableBean.carsSmall}">                    
    <p:columns value="#{tableBean.columns}" var="column" columnIndexVar="colIndex" 
                sortBy="#{car[column.property]}" filterBy="#{car[column.property]}">
        <f:facet name="header">
            #{column.header}
        </f:facet>

        #{car[column.property]}
    </p:columns>
</p:dataTable>
