java - 序列化 AbstractTableModel

Question

我正在尝试序列化 abstractTableModel 并且当我尝试将表格内容保存在文件中时，该文件已成功保存，但我猜它始终为空（或未正确保存），因为它的大小始终为 17KB，无论我保存为空还是满桌...

这是我的约会安排表的 GUI：

这是我的代码......我希望这不是问题，因为它有更多的行......

public class TerminiPanel extends JFrame implements ActionListener, Serializable {

static JPanel terminPanel;
static Calendar terminiCalendar = new GregorianCalendar();
static int dan = terminiCalendar.get(Calendar.DAY_OF_MONTH);
static int mesec = terminiCalendar.get(Calendar.MONTH);
static int godina = terminiCalendar.get(Calendar.YEAR);

JPanel buttonPanel;
JScrollPane scrollPane;
JButton saveBtn;
static JTable table;

TerminiPanel(JPanel thisPanel) {
    super();
    this.terminPanel = thisPanel;
    this.terminPanel.setLayout(new BorderLayout());

    switch (Listener.monthChoose.getSelectedIndex()) {
        case 0:
            mesecIme = "Januar";
            break;
        case 1:
            mesecIme = "Februar";
            break;
        case 2:

        case 10:
            mesecIme = "Novembar";
            break;
        default:

    String tb = "Zakazani za " + dan + "." + mesecIme + " " + Listener.yearChoose.getSelectedItem();
    TitledBorder titledBorder = new TitledBorder(tb);
    terminPanel.setBorder(titledBorder);

    ///////////// Mali panel za dugme "Sacuvaj"
    buttonPanel = new JPanel();
    saveBtn = new JButton("Sacuvaj");

        ////////// Listener za zakazivanje - cuvanje podataka iz tabele u file /////////////

    scrollPane = new JScrollPane(table);

public static void main(JPanel terminPanel2) {
    TableModel tp = new TerminiTableModel().tableModel;
    try {
        if (izabraniDan == null)
            izabraniDan = Integer.toString(dan);

        FileOutputStream fileOut = new FileOutputStream("" + izabraniDan + "" + (mesec + 1) + "" + godina + ".ser");

        ObjectOutputStream out = new ObjectOutputStream(fileOut);

        out.writeObject(tp);
        out.close();
        fileOut.close();

        JOptionPane.showMessageDialog(null, "Uspesno ste sacuvali zakazane pacijente za dan " + izabraniDan + "." + (mesec + 1) + "." + godina);

        } catch (IOException ioex) {
            ioex.printStackTrace();
        }   
}

}

我的 AbstractTableModel 在其他类中，如果需要，我也会上传它......我想知道我在哪里犯了错误，所以它不会保存我的表格内容，以及为什么点击后它甚至不加载空表在没有为自己保存文件的日期...

谢谢帮助...

PS：我编辑了代码......这是我所做的，现在没有错误，但它没有完成工作：-/
