Answer 2

我没有测试过，但我找到了一个例子：

http://www.primefaces.org/showcase/ui/data/datatable/group.xhtml

<p:dataTable var="sale" value="#{dtGroupView.sales}">
    <f:facet name="header">
        Sales/Profits of Manufacturers
    </f:facet>

    <p:columnGroup type="header">
        <p:row>
            <p:column colspan="1" headerText="items" />
            <p:column colspan="1" headerText="another" />
        </p:row>
        <p:row>
            <p:column rowspan="4" headerText="Manufacturer" />
        </p:row>
    </p:columnGroup>

    <p:column>
        <h:outputText value="#{sale.item1}" />
    </p:column>
    <p:column>
        <h:outputText value="#{sale.rowsOf4}%" />
    </p:column>

</p:dataTable>
