如何从jComboBox查询jTable？

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class ComboBoxTableExample extends JFrame {
    private JComboBox<String> comboBox;
    private JTable table;
    private DefaultTableModel tableModel;

    public ComboBoxTableExample() {
        setTitle("ComboBox Table Example");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        // 创建jComboBox并添加选项
        comboBox = new JComboBox<>();
        comboBox.addItem("Option 1");
        comboBox.addItem("Option 2");
        comboBox.addItem("Option 3");

        // 创建jTable并设置数据模型
        tableModel = new DefaultTableModel();
        tableModel.addColumn("Column 1");
        tableModel.addColumn("Column 2");
        table = new JTable(tableModel);

        // 创建查询按钮
        JButton searchButton = new JButton("Search");
        searchButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String selectedValue = (String) comboBox.getSelectedItem();
                filterTable(selectedValue);
            }
        });

        // 添加组件到界面
        add(comboBox, BorderLayout.NORTH);
        add(new JScrollPane(table), BorderLayout.CENTER);
        add(searchButton, BorderLayout.SOUTH);

        pack();
        setVisible(true);
    }

    private void filterTable(String selectedValue) {
        // 清空原有数据
        tableModel.setRowCount(0);

        // 遍历jTable的每一行数据
        for (int i = 0; i < table.getRowCount(); i++) {
            // 判断某一列的值是否与选中的值相等
            if (table.getValueAt(i, 0).equals(selectedValue)) {
                // 添加匹配的行数据到新的jTable
                Object[] rowData = new Object[table.getColumnCount()];
                for (int j = 0; j < table.getColumnCount(); j++) {
                    rowData[j] = table.getValueAt(i, j);
                }
                tableModel.addRow(rowData);
            }
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new ComboBoxTableExample();
            }
        });
    }
}
