To reach this aim, there is the method fieldname__permissions to place into the delegate class of the table. 

===Getting the role===

First it is necessary to know the user's role. For this, the method getUser() is added in the class :
<code>function getUser(&$record){
  $auth =& Dataface_AuthenticationTool::getInstance();
    $user =& $auth->getLoggedInUser();
return $user;
}</code>


===Setting up the permissions for each field===

Next, the permissions are built for each column or field where they are needed, like in this example where the method name is formed with the field name, followed by 2 underscores then by ''permissions'' :

<code>function fieldname__permissions(&$record){

$the_user =$this->getUser($record);
$user=$the_user->val('identifiant');
if ( !$user) return Dataface_PermissionsTool::NO_ACCESS();

    if ( $user=='demande' ){
        return Dataface_PermissionsTool::ALL();
    } elseif ($user=='admin'){
 return Dataface_PermissionsTool::ALL();
}
else {
        return Dataface_PermissionsTool::READ_ONLY();
    }
}</code>
