具体代码StudentAddInterFrm studentAddInterFrm = new StudentAddInterFrm(); table.add(studentAddInterFrm); studentAddInterFrm.setVisible(true);

根据您提供的代码，您的`StudentAddInterFrm`应该是一个`JInternalFrame`。如果您将`StudentAddInterFrm`添加到`table`中，`table`应该是一个`JDesktopPane`或其子类的对象。

在这种情况下，确保`table`已添加到您的外部窗口中，例如`JFrame`或`JDialog`。然后，请确保`StudentAddInterFrm`已设置为可见性（即`setVisible(true)`）。如果`StudentAddInterFrm`的大小或位置不正确，您可以使用`setBounds`方法或其他相关方法进行调整。

如果您的代码仍然无法解决问题，请提供更多详细信息，例如完整的代码或错误信息，以便我更好地帮助您解决问题。

您可以在 JTable 中添加一个新的列，用来显示删除和修改的按钮。在 actionPerformed() 方法中，您可以为每一行添加对应的按钮，并添加相应的 ActionListener。以下是您可以参考的修改代码：

public class InterfaceCallExample extends JFrame implements ActionListener {

    private static final long serialVersionUID = 1L;
    private JButton callButton;
    private JTable resultTable;
    private DefaultTableModel tableModel;

    public InterfaceCallExample() {
        super("Interface Call Example");
        setSize(800, 600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        callButton = new JButton("查看数据");
        callButton.addActionListener(this);
        panel.add(callButton);
        add(panel, BorderLayout.NORTH);

        tableModel = new DefaultTableModel();
        tableModel.addColumn("id");
        tableModel.addColumn("材料类型");
        tableModel.addColumn("状态");
        tableModel.addColumn("创建时间");
        tableModel.addColumn("更改时间");
        tableModel.addColumn("删除");
        tableModel.addColumn("修改");

        resultTable = new JTable(tableModel);
        add(new JScrollPane(resultTable), BorderLayout.CENTER);
    }

    public static void main(String[] args) {
        InterfaceCallExample example = new InterfaceCallExample();
        example.setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == callButton) {
            try {
                URL url = new URL("http://101.34.120.182:8081/wnapp/productType/getTypeId?category=1&status=0&type=");
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("GET");
                BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                String s = reader.readLine();
                JSONObject jsonObject = new JSONObject();
                JSONObject object = JSONObject.parseObject(s);
                Object o = object.get("data");
                JSONObject object1 = JSONObject.parseObject(o.toString());
                ArrayList<Map<String,Object>> list = (ArrayList<Map<String,Object>>) object1.get("list");
                for (Map<String,Object> map : list){
                    String id = map.get("id").toString();
                    String titleName = map.get("titleName").toString();
                    String status = map.get("status").toString();
                    String createTime = map.get("createTime").toString();
                    String updateTime = map.get("updateTime").toString();
                    
                    JButton deleteButton = new JButton("删除");
                    deleteButton.addActionListener(new DeleteActionListener(id));
                    JButton updateButton = new JButton("修改");
                    updateButton.addActionListener(new UpdateActionListener(id, titleName, status, createTime, updateTime));
                    
                    ArrayList<String> strings = new ArrayList<>();
                    strings.add(id);
                    strings.add(titleName);
                    strings.add(status);
                    strings.add(createTime);
                    strings.add(updateTime);
                    strings.add("");
                    strings.add("");

                    String[] data = strings.toString().replace("[","").replace("]","").split(",");
                    tableModel.addRow(data);
                    
                    int row = tableModel.getRowCount() - 1;
                    resultTable.setValueAt(deleteButton, row, 5);
                    resultTable.setValueAt(updateButton, row, 6);
                }
                reader.close();
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }
    
    class DeleteActionListener implements ActionListener {
        private String id;
        public DeleteActionListener(String id) {
            this.id = id;
        }
        @Override
        public void actionPerformed(ActionEvent e) {
            // TODO: 实现删除操作
        }
    }
    
    class UpdateActionListener implements ActionListener {
        private String id;
        private String titleName;
        private String status;
        private String createTime;
        private String updateTime;
        public UpdateActionListener(String id, String titleName, String status, String createTime, String updateTime) {
            this.id = id;
            this.titleName = titleName;
            this.status = status;
            this.createTime = createTime;
            this.updateTime = updateTime;
        }
        @Override
        public void actionPerformed(ActionEvent e) {
            // TODO: 实现修改操作
        }
    }
}

在 DeleteActionListener 和 UpdateActionListener 中，您可以实现相应的删除和修改操作。

帮我改写的能运行起来package com.swingtest; import java.awt.Container; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; import javax.swing.table.DefaultTableModel; public class StudentManger extends JFrame implements ActionListener { JLabel lstname = new JLabel("学生姓名: "); JTextField tf_name = new JTextField(12); JLabel lmajor = new JLabel("专业"); JTextField tf_major = new JTextField(); JButton btnOK = new JButton("添加"); JButton btnDelete = new JButton("删除"); JButton btnQuit = new JButton("退出"); JTable table; DefaultTableModel model; public void studentManger(String name) { // TODO Auto-generated constructor stub JLabel welcome = new JLabel(name +",欢迎登录！"); setTitle("学生管理"); setSize(400,400); welcome.setBounds(50,20,200,20); lstname.setBounds(50,20,200,20); tf_name.setBounds(150,50,100,20); lmajor.setBounds(50,80,100,20); tf_major.setBounds(150,80,100,20); btnOK.setBounds(80,110,60,20); btnDelete.setBounds(150,110,60,20); btnQuit.setBounds(220,110,60,20); Container c = getContentPane(); JPanel panel = new JPanel(); panel.setLayout(null); panel.add(welcome); panel.add(lstname); panel.add(tf_name); panel.add(lmajor); panel.add(tf_major); panel.add(btnOK); panel.add(btnDelete); panel.add(btnQuit); String[] colName = {"姓名","专业"}; model = new DefaultTableModel(colName,0); table = new JTable(model); JScrollPane scrollPane = new JScrollPane(table); c.setLayout(new SpringLayout()); c.add(panel); c.add(scrollPane); setLocationRelativeTo(null); setVisible(true); btnOK.addActionListener(this); btnDelete.addActionListener(this); btnQuit.addActionListener(this); } @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub Object ob = e.getSource(); if(ob == btnQuit) { System.exit(0); }else if(ob ==btnOK) { String[] stuInfo = {tf_name.getText(),tf_major.getText()}; model.addRow(stuInfo); tf_name.setText(""); tf_major.setText(""); }else if(ob == btnDelete) { if(table.getSelectedRow()<0) { JOptionPane.showMessageDialog(null,"请在表格中选中要删除的行");} else { model.removeRow(table.getSelectedRow()); } }} public static void main(String[] args) { new StudentManger(); } }

改写后的代码如下：

package com.swingtest;

import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.*;
import javax.swing.table.DefaultTableModel;

public class StudentManager extends JFrame implements ActionListener {

    private JLabel welcomeLabel;
    private JLabel nameLabel;
    private JTextField nameTextField;
    private JLabel majorLabel;
    private JTextField majorTextField;
    private JButton addButton;
    private JButton deleteButton;
    private JButton quitButton;
    private JTable table;
    private DefaultTableModel model;

    public StudentManager(String name) {
        welcomeLabel = new JLabel(name + ",欢迎登录！");
        nameLabel = new JLabel("学生姓名: ");
        nameTextField = new JTextField(12);
        majorLabel = new JLabel("专业");
        majorTextField = new JTextField();
        addButton = new JButton("添加");
        deleteButton = new JButton("删除");
        quitButton = new JButton("退出");
        String[] colName = {"姓名", "专业"};
        model = new DefaultTableModel(colName, 0);
        table = new JTable(model);
        JScrollPane scrollPane = new JScrollPane(table);

        setTitle("学生管理");
        setSize(400, 400);
        setLocationRelativeTo(null);
        setVisible(true);

        welcomeLabel.setBounds(50, 20, 200, 20);
        nameLabel.setBounds(50, 50, 100, 20);
        nameTextField.setBounds(150, 50, 100, 20);
        majorLabel.setBounds(50, 80, 100, 20);
        majorTextField.setBounds(150, 80, 100, 20);
        addButton.setBounds(80, 110, 60, 20);
        deleteButton.setBounds(150, 110, 60, 20);
        quitButton.setBounds(220, 110, 60, 20);

        Container c = getContentPane();
        JPanel panel = new JPanel();
        panel.setLayout(null);
        panel.add(welcomeLabel);
        panel.add(nameLabel);
        panel.add(nameTextField);
        panel.add(majorLabel);
        panel.add(majorTextField);
        panel.add(addButton);
        panel.add(deleteButton);
        panel.add(quitButton);
        c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS));
        c.add(panel);
        c.add(scrollPane);

        addButton.addActionListener(this);
        deleteButton.addActionListener(this);
        quitButton.addActionListener(this);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        Object ob = e.getSource();
        if (ob == quitButton) {
            System.exit(0);
        } else if (ob == addButton) {
            String[] stuInfo = {nameTextField.getText(), majorTextField.getText()};
            model.addRow(stuInfo);
            nameTextField.setText("");
            majorTextField.setText("");
        } else if (ob == deleteButton) {
            if (table.getSelectedRow() < 0) {
                JOptionPane.showMessageDialog(null, "请在表格中选中要删除的行");
            } else {
                model.removeRow(table.getSelectedRow());
            }
        }
    }

    public static void main(String[] args) {
        new StudentManager("张三");
    }
}

改写后的代码主要是对变量名和方法名进行规范化、重构，同时对布局管理器进行了修改，更加灵活。程序的功能并没有变化，仅仅是代码更加规范、易读。
