I changed your code a bit to show you what you were doing wrong, you need to implement KeyListener:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import javax.swing.text.*;
import javax.swing.event.*;
import javax.swing.table.*;
import java.util.EventObject;
public class Test extends JFrame implements KeyListener {
public JTable table;
public JScrollPane scrollpane;
public Test() {
JTextField editor;
this.table = new JTable(5,5);
this.scrollpane=new JScrollPane(table);
for (int i=0;i<5;i++) {
editor=new JTextField();
editor.setBackground(Color.blue);
editor.setForeground(Color.white);
editor.addKeyListener( this ); //addkeylistener
this.table.getColumnModel().getColumn(i).setCellEditor(new DefaultCellEditor(editor));
this.getContentPane().add(this.scrollpane);
this.scrollpane.setVisible(true);
this.setSize(300,300);
this.setVisible(true);
public static void main(String args[]){
Test test=new Test();
public void keyReleased(KeyEvent e) {
System.out.println("keyReleased...");
public void keyPressed(KeyEvent e) {
System.out.println("keyPressed...");
public void keyTyped(KeyEvent e){
System.out.println("keytype...");
