我得到了使用过滤器的 primefaces 数据表。一切正常。但是当我将数据表导出到 excel 文件时，没有显示标题。

这里我使用 external remoteCommand 来处理服务器端的事件。

这是xhtml代码：

<h:form>
        <p:commandButton value="#{dictionary['export_to_excel']}" icon="ui-icon-calculator" ajax="false">
                                <p:dataExporter type="xls" target=":gwsReportAllPartForm:gwsReportAllPartListDataTable" fileName="analytics"/>  
                            </p:commandButton>  
                        </h:form>

<h:form id="gwsReportAllPartForm">
                            <p:remoteCommand name="updateFilters" update=":gwsReportAllPartForm:gwsReportAllPartListDataTable"></p:remoteCommand>
                        <p:dataTable  id="gwsReportAllPartListDataTable" 
                                      value="#{viewAllAnalyticsBean.gwsReportPartTwoList}"

尝试在 中使用f:facetinsteadheaderText属性p:column，例如：

<p:column>
   <f:facet name="header">
      <h:outputText id="header1" value="#{dictionary['some_key']}" />
   </f:facet>
   ...
</p:column>
