primefaces-编辑不含一个单元格的行

Question

我有行编辑的dataTable，但我不需要编辑我的一个单元格（user.username）。我怎样才能做到这一点？这可能吗？我尝试删除一个单元格的p:cellEditor，但它在我的平板电脑上不起作用，因为当我在DataTable中使用它时，该列为空。

谢谢

我的代码：

<h:form id="form">
        <p:growl id="messages" showDetail="true" />
        <p:contextMenu for="dataTable">
            <p:menuitem value="Delete" update="dataTable" icon="ui-icon-close"
                actionListener="#{userMB.deleteUser}" />
        </p:contextMenu>
        <p:dataTable id="dataTable" var="user" styleClass="DataTableUsers"
            value="#{userMB.userList}" paginator="true" rows="5"
            rowKey="#{user.user_id}" selection="#{userMB.selectedUser}"
            selectionMode="single" filteredValue="#{userMB.filteredUsers}"
            editable="true"
            paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
            rowsPerPageTemplate="5,10,15">
            <p:ajax event="rowEdit" immediate="true" listener="#{userMB.onEdit}"
                update=":form:messages, :form:dataTable" process="@this" />
            <p:column sortBy="name" filterBy="name" id="name" headerText="Name">

只需将保存user.username值的组件更改为

<h:outputText value="#{user.username}" />

您将拥有只读的值。
