我正在尝试使用单元格编辑创建 PrimeFaces p:dataTable。也许我使用了错误的语法或错误的绑定？带有数据表的 Html 代码：
<p:dataTable editable="true" editMode="cell" id="temperatureTable"
value="#{firingBean.temperatureMap}" var="temperatureRow" widgetVar="table">
<f:facet name="header">
Температурная карта
</f:facet>
<p:column styleClass="notEditable ui-state-default" width="30">
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<f:facet name="output">
<h:outputText value="#{dataSheet.rowIndex + 1}" />
</f:facet>
</p:column>
<p:column styleClass="notEditable" width="50">
<f:facet name="header">

</p:column>
</p:dataTable>
但是表格重新渲染了空行，而单元格和错误中没有可见值。怎么了？我正在使用 PrimeFaces 4.0。
