Java 如何创建具有素数面的矩阵表格（3D表格）？

我发现了同样的问题，我也试着为我的项目做同样的事情，但我无法得到结果，有人能检查我下面的代码并告诉我哪里出错了吗。 我想做的是得到一个表格，其中列是飞机，行是每架飞机的工作包，单元格是每架飞机的每个工作包中的作业。 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">
