Answer 1

import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

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

public class ButtonTable extends JFrame{

private static final long serialVersionUID = 1L;
private JTable table = null;
private DefaultTableModel model=null;
private JScrollPane js=null ;
public ButtonTable(){
model = new DefaultTableModel(3,3);
table = new JTable(model);
table.getColumnModel().getColumn(1).setCellEditor(new MyRender());//设置编辑器
table.getColumnModel().getColumn(1).setCellRenderer(new MyRender() );
js = new JScrollPane(table);

this.add(js);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setSize(399, 300);
this.setLocationRelativeTo(null);
}

public static void main(String[] args) {
// TODO Auto-generated method stub
new ButtonTable();
}

}

//渲染 器 编辑器
class MyRender extends AbstractCellEditor implements TableCellRenderer,ActionListener, TableCellEditor{

private static final long serialVersionUID = 1L;
private JButton button =null;
public MyRender(){
button = new JButton("确定不？");
button.addActionListener(this);
}

@Override
public Object getCellEditorValue() {
// TODO Auto-generated method stub
return null;
}

@Override
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
// TODO Auto-generated method stub
return button;
}

@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
JOptionPane.showMessageDialog(null, "渲染器学期", "消息", JOptionPane.OK_OPTION);

}

@Override
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
// TODO Auto-generated method stub
return button;
}

}
