Question

我尝试使用单元格编辑创建PrimeFaces p：dataTable。也许我使用错误的语法或错误的绑定？带有dataTable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">

            </h:inputText>
            </f:facet>
        </p:column>
    </p:dataTable>

但是表格在单元格和错误中没有可见值的empy行。怎么了？我使用的是PrimeFaces 4.0。

dataTable Error

Answer 1

<p:column styleClass="notEditable ui-state-default" width="30">
 <p:cellEditor>
    <f:facet name="input">
            <h:outputText value="" />
        </f:facet>
        <f:facet name="output">
            <h:outputText value="#{dataSheet.rowIndex + 1}" />
        </f:facet>
  </<p:cellEditor>
</p:column>

您没有使用 p：cellEditor 空白数据表的原因 Follow the link

PrimeFaces 4.0 p：dataTable不显示行数（空行）
