primefaces - 하나의 셀이없는 행을 편집하십시오.

Question

행 편집으로 dataTable을 가지고 있지만 셀 중 하나를 편집하지 않아도됩니다. (사용자. 사용자 이름). 어떻게하면 프라임면에서이 작업을 수행 할 수 있습니까? 이것이 가능한가? p : cellEditor을 하나의 셀에만 제거하려고 시도하지만 DataTable에서 사용할 때이 열은 비어 있기 때문에 타블렛에서는 작동하지 않습니다.

감사합니다.

내 코드 :

<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"

Answer 1

그냥 <h:outputText>

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

에 user.username 값을 보유하고있는 구성 요소를 변경하고 값이 읽기 전용이됩니다.
