Save a JTable (data+settings) ?

Question

I want to save a complete JTable.
In my JTable I changed all,
that means I changed the hight of a row and the length from a coloumn to have the best view of the data.
I want to save the table with this changes.
I used for the JTable the AbstractTableModel.
I tried to save and load the AbstractTableModel Object with the ObjectOutputStream but it doesn't worked.
Only the Coloumnames was showing, but that's all.
I hope somebody can help me

Your post gave me an idea and I didn't think it would work, but it seems to have done just fine. There has to be something wrong with this. It's too bizarre.import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class Test3 extends JFrame {
  String[] head = {"One","Two","Three"};
  String[][] data = {{"R1-C1","R1-C2","R1-C3"},
                     {"R2-C1","R2-C2","R2-C3"},
                     {"R3-C1","R3-C2","R3-C3"}};
  JTable jt = new JTable(data, head);
  byte[] bytes;
  Container content = getContentPane();
  int count = 0;
  public Test3() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    content.add(new JScrollPane(jt), BorderLayout.CENTER);
    JPanel buttonPanel = new JPanel();
    content.add(buttonPanel, BorderLayout.SOUTH);
    JButton save = new JButton("Save"), restore = new JButton("Restore");
    buttonPanel.add(save);
    buttonPanel.add(restore);
    save.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent ae) {
        try {
          ByteArrayOutputStream baos = new ByteArrayOutputStream();
          ObjectOutputStream oos = new ObjectOutputStream(baos);
          oos.writeObject(jt);
          oos.flush();
          oos.close();
          bytes = baos.toByteArray();
          content.add(new JPanel(), BorderLayout.CENTER);
          content.validate();
        } catch (Exception e) { e.printStackTrace(); }
    restore.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent ae) {
        try {
          ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
          ObjectInputStream ois = new ObjectInputStream(bais);
          JTable newTable = (JTable)ois.readObject();
          content.add(new JScrollPane(newTable), BorderLayout.CENTER);
          content.validate();
        } catch (Exception e) { e.printStackTrace(); }
    setSize(300,300);
  public static void main(String[] args) { new Test3().setVisible(true); }
}
