primefaces - 編輯沒有一個單元格的行

Question

我有dataTable與行編輯，但我不需要編輯我的單元格之一（user.username）。我怎樣才能在primefaces中做到這一點？這可能嗎？我嘗試刪除p：cellEditor對於一個單元格，但它不適用於我的平板電腦，因爲當我在DataTable中使用此列時，此列爲空。

謝謝！

我的代碼：

<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"> 
       <p:cellEditor> 
        <f:facet name="output">

       </p:cellEditor> 
      </p:column> 
      <p:column style="width:6%" headerText="Edit"> 
       <p:rowEditor /> 
      </p:column> 
      <f:facet name="footer"> 
       <p:commandButton value="New User" oncomplete="newUserDialog.show()" 
        icon="ui-icon-star" title="Creates new user" /> 

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

Answer 1

持有的user.username值的組件就變成<h:outputText>

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

，你將有值爲只讀。
