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。
