### 一：自定义类MyCellRender实现接口TableCellRenderer，重写组件方法 ###

import java.awt.Component;
    
    import javax.swing.Icon;
    import javax.swing.JLabel;
    import javax.swing.JTable;
    import javax.swing.table.TableCellRenderer;
    
    import com.uplooking.util.UtilTest;
    
    public class MyCellRender implements TableCellRenderer {
        
    
    	@Override
    	public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
    			int row, int column) {
        
    		if (value == null) {
        
    			JLabel lbl = new JLabel("未有添加");
    			lbl.setHorizontalAlignment(JLabel.CENTER);
    			lbl.setVerticalAlignment(JLabel.BOTTOM);
    			return lbl;
    		}
    		Icon icon = UtilTest.getIcon(value.toString());
    		JLabel photo = new JLabel(icon);
    		return photo;
    	}
    
    }

### 二：UTilTest类中getIcon方法获取对象 ###

public static Icon getIcon(String name) {
        
    	Image image = getImage(name);
    	Icon icon =new ImageIcon(image);
    	return icon;
    }

### 三：UTilTest类中getImage方法获取图片 ###

public static Image getImage(String name) {
        
    	URL url = UtilTest.class.getClassLoader()
    			.getResource("images/" +name);
    	Image image  =Toolkit.getDefaultToolkit().getImage(url);
    	return image;
    }

### 四：在JTable对象实现： ###

道可道非常道，名可名非常名。  
众人皆有已，而我独顽且鄙。
