Il y a une belle GridFieldManager par Anthony Rizk.

code:

public void list() 
    { 
     if (null != mGrid && null != mGrid.getManager()) 
      mGrid.getManager().delete(mGrid); 
     int colWidth = net.rim.device.api.system.Display.getWidth()/4; 
     mGrid = new GridFieldManager(new int[] { 0, colWidth, colWidth, 
       colWidth, colWidth }, VERTICAL_SCROLL | VERTICAL_SCROLLBAR); 
     mGrid.add(new NullField(FOCUSABLE)); 
     mGrid.add(new LabelField("Name")); 
     mGrid.add(new LabelField("E-Mail")); 
     mGrid.add(new LabelField("Gender")); 
     mGrid.add(new LabelField("Active")); 
     add(mGrid); 
     _data = (Vector) store.getContents(); 
     try { 
      int sn = 0; 
      for (int i = _data.size() - 1; i > -1; i--, sn++) { 

       StoreInfo info = (StoreInfo) _data.elementAt(i); 
       // checking for empty object 
       if (!_data.isEmpty()) { 
        // if not empty 
        // create a new object of Store Info class 

        // storing information retrieved in strings 
        firstUserName = (info.getElement(StoreInfo.NAME)); 
        lastUserName = (info.getElement(StoreInfo.LastNAME)); 
        userEmail = (info.getElement(StoreInfo.EMail)); 
        userGender = (info.getElement(StoreInfo.GenDer)); 
        userStatus = (info.getElement(StoreInfo.setStatus)); 

        // calling the listAll method 
        mGrid.add(new NullField(FOCUSABLE)); 
        mGrid.add(new LabelField(firstUserName + " " 
          + lastUserName)); 
        mGrid.add(new LabelField(userEmail)); 
        mGrid.add(new LabelField(userGender)); 
        mGrid.add(new LabelField(userStatus)); 
       } 

      }
