可以在表格中添加一个新的列，用于显示每一行的“删除”和“修改”按钮。每当添加一行数据时，就在该列中添加对应的按钮。以下是修改后的代码：

public class InterfaceCallExample extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    private JButton callButton;
    private JTable resultTable;
    private DefaultTableModel tableModel;
    private JButton[] editButtons; // 修改按钮
    private JButton[] deleteButtons; // 删除按钮

    public InterfaceCallExample() {
        super("Interface Call Example");
        setSize(500, 300);
        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("操作"); // 操作列
        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");

                int rowCount = tableModel.getRowCount();
                for (int i = 0; i < rowCount; i++) {
                    tableModel.removeRow(0);
                }
                editButtons = new JButton[list.size()];
                deleteButtons = new JButton[list.size()];
                for (int i = 0; i < list.size(); i++) {
                    Map<String,Object> map = list.get(i);
                    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();
                    ArrayList<String> strings = new ArrayList<String>();
                    strings.add(id);
                    strings.add(titleName);
                    strings.add(status);
                    strings.add(createTime);
                    strings.add(updateTime);
                    String[] data = strings.toString().replace("[","").replace("]","").split(",");
                    tableModel.addRow(data);

                    // 添加修改按钮
                    editButtons[i] = new JButton("修改");
                    editButtons[i].addActionListener(new EditButtonActionListener(tableModel, i));
                    resultTable.setValueAt(editButtons[i], i, 5);

                    // 添加删除按钮
                    deleteButtons[i] = new JButton("删除");
                    deleteButtons[i].addActionListener(new DeleteButtonActionListener(tableModel, i));
                    resultTable.setValueAt(deleteButtons[i], i, 6);
                }
                reader.close();
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }

    // 修改按钮事件处理器
    private class EditButtonActionListener implements ActionListener {
        private DefaultTableModel tableModel;
        private int row;

        public EditButtonActionListener(DefaultTableModel tableModel, int row) {
            this.tableModel = tableModel;
            this.row = row;
        }

        @Override
        public void actionPerformed(ActionEvent e) {
            // TODO: 实现修改操作
            System.out.println("修改第" + row + "行数据");
        }
    }

    // 删除按钮事件处理器
    private class DeleteButtonActionListener implements ActionListener {
        private DefaultTableModel tableModel;
        private int row;

        public DeleteButtonActionListener(DefaultTableModel tableModel, int row) {
            this.tableModel = tableModel;
            this.row = row;
        }

        @Override
        public void actionPerformed(ActionEvent e) {
            tableModel.removeRow(row);
        }
    }
}

在上述代码中，我们添加了两个内部类 `EditButtonActionListener` 和 `DeleteButtonActionListener`，分别用于处理“修改”和“删除”按钮的事件。在 `actionPerformed` 方法中，我们将每一行的“修改”和“删除”按钮添加到表格中，同时为每个按钮添加相应的事件处理器。当用户单击“修改”或“删除”按钮时，相应的事件处理器会被触发，从而实现对数据的修改或删除。
