无需创建自定义渲染。JTable已经支持Icon渲染器。您只需要告诉表使用此渲染器即可。这是通过重写表模型的getColumnClass（…）方法来完成的：
import java.awt.*;import javax.swing.*;import javax.swing.table.*;public class TableIcon extends JPanel{ public TableIcon() { Icon aboutIcon = new ImageIcon("about16.gif"); Icon addIcon = new ImageIcon("add16.gif"); Icon copyIcon = new ImageIcon("copy16.gif"); String[] columnNames = {"Picture", "Description"}; Object[][] data = { {aboutIcon, "about"}, {addIcon, "Add"}, {copyIcon, "Copy"}, }; DefaultTableModel model = new DefaultTableModel(data, columnNames) { // Returning the Class of each column will allow different // renderers to be used based on Class public Class getColumnClass(int column) { return getValueAt(0, column).getClass(); } }; JTable table = new JTable( model ); table.setPreferredScrollableViewportSize(table.getPreferredSize()); JScrollPane scrollPane = new JScrollPane( table ); add( scrollPane ); } private static void createAndShowGUI() { Jframe frame = new Jframe("Table Icon"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.add(new TableIcon()); frame.setLocationByPlatform( true ); frame.pack(); frame.setVisible( true ); } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); }}
