JTable中不同单元格中的不同imageIcon

我想我的imageIcon在每个单元格中都有不同的显示方式，但出于某种原因，当我编译它时，图像不会显示出来。 它显示图像的名称，但图像本身不显示。 这是一张图片。 http://sofzh.miximages.com/java/r9ibrn.jpg

public class movies extends JFrame { public movies() { initComponents(); } private void initComponents() { panel = new JPanel(); logo = new JLabel(); pane = new JScrollPane(); setDefaultCloseOperation(EXIT_ON_CLOSE); setBackground(new Color(255, 255, 204)); setResizable(false); panel.setBackground(new Color(51, 51, 51)); panel.setPreferredSize(new Dimension(290, 75)); logo.setIcon(new ImageIcon(getClass().getResource("logo.png"))); logo.setName("logo"); logo.setRequestFocusEnabled(false); logo.setVerifyInputWhenFocusTarget(false); logo.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); ImageIcon icon1 = new ImageIcon("1.jpg"); ImageIcon icon2 = new ImageIcon("2.jpg"); ImageIcon icon3 = new ImageIcon("3.jpg"); String[] columnNames = {"Section 1", "Section 2"}; Object[][] data = { {icon1 + " Music", icon2 + " News"}, {icon2 + " Movies"}, {icon3 + " Games"}, }; DefaultTableModel model = new DefaultTableModel(data, columnNames); JTable table = new JTable( model ) { public Class getColumnClass(int column) { return getValueAt(0, column).getClass(); } }; table.setPreferredScrollableViewportSize(table.getPreferredSize()); table.setBackground(new Color(255, 255, 204)); JScrollPane scrollPane = new JScrollPane( table ); getContentPane().add( scrollPane ); table.setRowHeight(50); pane.setViewportView(table); table.getColumnModel().getColumn(0).setResizable(false); table.getColumnModel().getColumn(1).setResizable(false); } public static void main(String args[]) { public void run() { new movies().setVisible(true); } }); } private JLabel logo; private JScrollPane pane; private JPanel panel; 

}

调用new ImageRenderer构造函数时，可以传入图像的名称（ 读取此内容 ）。

 public class Movies extends javax.swing.JFrame { public Movies() { initComponents(); table.getColumnModel().getColumn(1).setCellRenderer(new ImageRenderer("1.jpg")); table.getColumnModel().getColumn(0).setCellRenderer(new ImageRenderer("2.jpg")); } } class ImageRenderer extends DefaultTableCellRenderer { ImageIcon icon = null; ImageRenderer(String iconName) { icon = new ImageIcon(getClass().getResource(iconName)); } }
