Table does not fit into JScrollPane...

Question

Hello,
I created a JTable and want to put this table into a JScrollPane, because the table is larger than the screen-size. The problem is that I never get the horizontal ScrollBar displayed, and the columns of my table are pressed together.
Just try yourself, here's a piece of my source code:
JTable table = new JTable(100,100);
JScrollPane pane = new JScrollPane(table);
I tried different constructor-versions of the JScrollPane-object, but the result was always the same: very very small columns and no horizontal ScrollBar.
Who can tell me how to do so...? I'd be very pleased about any kind of
advision because this problem really drives me crazy...
Thanx, Findus

Hi,
The reason that the horizontal scrollbar is not appearing is because you have the columns as resizeable. By default the column are automatically resizeable. You have to switch off the resizing.
The code should be something like this (an example)
import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.JScrollPane;
public class MyFrame extends JFrame {
private JTable table = null;
public MyFrame() {
try{
GUI();
catch(Exception ex) {
ex.printStackTrace();
private void GUI() throws Exception {
table = new JTable(100, 100);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
this.getContentPane().add(new JScrollPane(table);
this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
this.setSize(400, 400);
this.setVisible(true);
public static void main(String[] args) {
MyFrame app = new MyFrame();
I hope this helps
