好的，您可以在构造函数中添加一个新的按钮，并为其添加一个监听器，如下所示：

public class InterfaceCallExample extends JFrame implements ActionListener {

    // 省略原有的代码

    private JButton callButton;
    private JButton addButton; // 新增按钮

    // 省略原有的代码

    public InterfaceCallExample() {
        super("Interface Call Example");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel panel = new JPanel();
        callButton = new JButton("查看数据");
        callButton.addActionListener(this);
        panel.add(callButton);

        addButton = new JButton("新增数据"); // 新增按钮
        addButton.addActionListener(this); // 新增按钮监听器
        panel.add(addButton); // 新增按钮

        add(panel, BorderLayout.NORTH);

        // 省略原有的代码
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == callButton) {
            // 省略原有的代码
        } else if (e.getSource() == addButton) { // 处理新增按钮点击事件
            String id = "xxx"; // 新增数据的id
            String titleName = "xxx"; // 新增数据的材料类型
            String status = "xxx"; // 新增数据的状态
            String createTime = "xxx"; // 新增数据的创建时间
            String updateTime = "xxx"; // 新增数据的更改时间
            ArrayList<String> strings = new ArrayList<>();
            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); // 添加新增数据到表格中
        }
    }
}

这样就实现了一个新增数据的功能按钮。当用户点击该按钮时，程序会添加一条新的数据到表格中。
