如何在JTable列中设置图标？
我能够设置列的标题，但无法在JTable的第一列的所有行中设置图标。
public class iconRenderer extends DefaultTableCellRenderer{
public Component getTableCellRendererComponent(JTable table,Object obj,boolean isSelected,boolean hasFocus,int row,int column){
imageicon i=(imageicon)obj;
if(obj==i)
setIcon(i.imageIcon);
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
setHorizontalAlignment(JLabel.CENTER);
return this;
}
}
public class imageicon{
ImageIcon imageIcon;
imageicon(ImageIcon icon){
imageIcon=icon;
}
}
public void SetIcon(JTable table, int col_index, ImageIcon icon){
table.getTableHeader().getColumnModel().getColumn(col_index).setHeaderRenderer(new iconRenderer());
table.getColumnModel().getColumn(col_index).setHeaderValue(new imageicon(icon));
}

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(); } }); } }倪蕊悲潍
。 http://download.oracle.com/javase/6/docs/api/javax/swing/table/TableColumn.html#setCellRenderer(javax.swing.table.TableCellRenderer） 附注：Java编码标准规定类名应以大写字母开头，因此应为。
