我正在写一个关于管理学生的程序，但是当我添加一个新学生时，模型仍然获得所有数据，但是JTable没有显示新添加的学生。我花了更多的时间来修复和检测错误，但是我什么也没有得到。谁能帮助我解决这个问题？
下面是我的代码。

package javaswing;

import java.util.ArrayList;
import javax.swing.table.AbstractTableModel;

/**
 *
 * @author ADMIN
 */
public class StudentModelTable extends AbstractTableModel {

    private ArrayList<Student> data = new ArrayList<>();
    private String[] columnNames;

    public StudentModelTable(ArrayList<Student> studentList) {
        super();
        data = studentList;
        columnNames = new String[]{"MHS", "Họ và tên", "Điểm", "Địa chỉ", "Ghi chú"};
    }

    @Override
    public int getRowCount() {
        return data.size();
    }

    @Override
    public int getColumnCount() {
        return columnNames.length;
    }

    @Override
    public Object getValueAt(int rowIndex, int columnIndex) {
        Student student = data.get(rowIndex);

        return switch (columnIndex) {
            case 0 ->
                student.getStudentCode();
            case 1 ->
                student.getFullname();
            case 2 ->
                student.getScore();
            case 3 ->
                student.getAddress();
            case 4 ->
                student.getNotice();
            default ->
                null;
        };
    }

    @Override
    public String getColumnName(int col) {
        return columnNames[col];
    }

    //set value at a particular cell 
    public void setValueAt(Student student, int row, int column) {
        data.add(row, student);
        fireTableCellUpdated(row, column);
    }
}

在这里，代码绘制表格

private void viewListStudentActionPerformed(java.awt.event.ActionEvent evt) {                                                
    // TODO add your handling code here:
    addStudent.setBorderPainted(false);
    updateStudent.setBorderPainted(false);
    viewListStudent.setBorderPainted(true);
    import_export.setBorderPainted(false);
    jTabbedPane1.setSelectedIndex(2);

    try {
        Launcher.dataTable = Util.readDataBinary();

        JTable tableStudennt = new JTable();

        if (Launcher.dataTable != null) {
            Launcher.dataTable = Util.sortArrayList(Launcher.dataTable, 0);

            // thiết lập data cho JTable
            this.modelTable = new StudentModelTable(Launcher.dataTable);
            System.out.println(this.modelTable.getRowCount());
            // vẽ JTable vào tab
            tableStudennt = new JTable(this.modelTable);
        } else {
            // Nếu dữ liệu null cần set table default
            tableStudennt.setModel(new DefaultTableModel(
                    new Object[][]{
                        {null, null, null, null, null, null, null},}, new String[]{"MHS", "Họ và tên", "Điểm", "Địa chỉ", "Ghi chú"}
            ));
        }

        tableStudennt.setColumnSelectionAllowed(false);
        tableStudennt.setFillsViewportHeight(true);
        JScrollPane scrollPane = new JScrollPane(tableStudennt);

        // thiết lập comboBox
        String[] modeStudentCode = {"MHS tăng dần", "MHS giảm dần", "Điểm tăng dần", "Điểm giảm dần"};

        JComboBox comboxStudentCode = new JComboBox(modeStudentCode);
        comboxStudentCode.setSelectedIndex(0);
        comboxStudentCode.setEditable(false);
        comboxStudentCode.addActionListener((java.awt.event.ActionEvent evt1) -> {
            Launcher.dataTable = Util.sortArrayList(Launcher.dataTable, comboxStudentCode.getSelectedIndex());
            this.modelTable.fireTableDataChanged();
        });

        tab4.add(comboxStudentCode, new org.netbeans.lib.awtextra.AbsoluteConstraints(0, 120, -1, -1));
        tab4.add(scrollPane, new AbsoluteConstraints(0, 160, 780, 400));
    } catch (IOException | ClassNotFoundException ex) {
        Logger.getLogger(Launcher.class.getName()).log(Level.SEVERE, null, ex);
    }
}
