为什么我的jtable中不能显示图片（只显示路径字符串）？？？（附源码）
代码如下
package com.nfs;


import java.awt.*; 
import java.util.Vector;

import javax.swing.*; 
import javax.swing.event.*; 
import javax.swing.table.*; 

public class TestSimpleJTable { 
private static DefaultTableModel tableModel1 = new DefaultTableModel() { 
  public boolean isCellEditable(int row, int col) { 
  if (col == 1) { 
  return true; 
  } 
  else { 
  return false; 
  } 
  }//使得第二列的单元格子可编辑，其他列的单元格子不可编辑 

// public Class getColumnClass(int col) { 
// Vector v=(Vector)dataVector.elementAt(0); 
// return v.element(col).getClass(); 
// } 

  public Class getColumnClass(int c) { 
  return getValueAt(0, c).getClass(); 
  }//可以使单元格子实现Image,CheckBox等 
  };  

  private JTable jTable1 = new JTable(tableModel1);  


  public static void main(String[] args) { 
  String[][] data = {{"A", "B"}, {"C", "D"}}; 
  String[] colName = {"First", "Last"}; 

  JFrame frame = new JFrame(); 
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

  final JTextField field = new JTextField(); 
  JTable table = new JTable(data,colName){//(tableModel1){ 
   
  /**
* long
*/
private static final long serialVersionUID = 1L;

// JTable的RowSelectionChanged事件在这里。 
  public void valueChanged(ListSelectionEvent e) { 
  super.valueChanged(e); 

  if (!this.isVisible()) { 
  return; 
  } 

  ListSelectionModel sm = 
  (ListSelectionModel)e.getSource(); 
  int row = sm.getLeadSelectionIndex(); 

  int colCount = this.getColumnCount(); 
  String[] sa = new String[colCount]; 

  for (int col=0; col<colCount; col++) { 
  sa[col] = (String)this.getValueAt(row, col); 
  } 

  String s = ""; 
  for (int i=0; i<sa.length; i++) { 
  s += sa[i] + "\t"; 
  } 
  System.out.println("--->>>"+s);
  field.setText(s); 
  } 
  }; 

  JTable table1 = new JTable(tableModel1);
  tableModel1.addRow(new Object[] {new ImageIcon( "C:\\Documents and Settings\\Administrator\\My Documents\\My Pictures\\1.gif "), new Boolean(false), "John ", "male ", "23 "}); 
  tableModel1.addRow(new Object[]{"111","222","233","444","555"});
   
  Vector<String> columnNames = new Vector();
  // String[] m_colNames = { "子服务ID", "主服务ID",
  // "子服务名称","开始路径","日志路径","备注","是否启用","是否可视","创建时间"};
