我有一个具有列切换器的数据表。当我取消选中列并在字段上排序时，表是错误的。弹出未选中字段的标题，并且所有数据向左移动，从而使1列留空。

我的table.xhtml文件：

<h:form>    
    <p:dataTable id="registrations" var="registration" tableStyle="table-layout: auto;" widgetVar="registrationsTable" 
        value="#{overviewBean.listOfRegistrations}" 
        filteredValue="#{overviewBean.filteredListOfRegistrations}" emptyMessage="No registrations found with given criteria" >
        <f:facet name="header">
            <p:outputPanel style="text-align:left;">
                <h:outputText value="Search all fields: " />
                <p:inputText id="globalFilter" onkeyup="PF('registrationsTable').filter()" style="width:150px;" placeholder="Enter keyword"/>

                <p:commandButton id="toggler" type="button" value="Columns"  icon="ui-icon-calculator" style="float:right;"/>
                <p:columnToggler datasource="registrations" trigger="toggler" >
                </p:columnToggler>
            </p:outputPanel> 
        </f:facet>


        <p:column headerText="Active" visible="false">
            <h:outputText value="Y" />
        </p:column>

        <p:column headerText="Firstname" filterBy="#{registration.firstname}" filterStyle="display:none" sortBy="#{registration.firstname}">
            <h:outputText value="#{registration.firstname}" />
        </p:column>

        <p:column headerText="Lastname" filterBy="#{registration.lastname}" filterStyle="display:none" sortBy="#{registration.lastname}">
            <h:outputText value="#{registration.lastname}" />
        </p:column>

    </p:dataTable>
</h:form>
