我找到了同样的问题Here，我尝试为我的项目做同样的事情，但我无法得到结果，任何人都可以检查下面的代码并告诉我在哪里制作一个失误。 我想要做的是获得一个表格，其中列是飞机，行是每架飞机的工作包，单元格是每架飞机每个工作包中的工作。 XHTML是：
<h:form id="globalreport">
<p:layout>
<p:layoutUnit position="north">
<p:selectOneMenu id="model" value="#{userInterfaceMB.model}">
<f:selectItem itemLabel="All models" itemValue="" />
<f:selectItems value="#{userInterfaceMB.getAllAvailableModels()}" />
<p:ajax update="aircraftTable"listener="#{userInterfaceMB.handleModelChange()}" />
</p:selectOneMenu>
</p:layoutUnit>
<p:layoutUnit position="center">
<p:dataTable id="aircraftTable" var="workPackageId"
value="# {userInterfaceMB.workPackagesIds}" rowIndexVar="rowIdx">
<p:column headerText="" styleClass="ui-widget-header">
<h:outputText value="#{workPackageId}" />
</p:column>
<p:columns var="aircraftId" value="#
{userInterfaceMB.aircraftsIds}"
headerText="#{aircraftId}"
columnIndexVar="colIdx">
<ui:repeat value="#{userInterfaceMB.myJobs[rowIdx][colIdx]}"
var="myJob">
<p:panel>
<h:outputText value="#{myJob}" />
</p:panel>
</ui:repeat>
</p:columns
</p:dataTable>
</p:layoutUnit>
</p:layout>
</h:form>
</h:body>
