如何在Java Swing中设置JTable单元格的两种背景色

import javax.swing.*;
import javax.swing.table.DefaultTableCellRenderer;

public class MyTableCellRenderer extends DefaultTableCellRenderer {
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        Component component = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        
        // 设置奇数行的背景色为灰色
        if (row % 2 == 1) {
            component.setBackground(Color.LIGHT_GRAY);
        } else {
            component.setBackground(Color.WHITE);
        }
        
        return component;
    }
}

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        JTable table = new JTable(10, 5);
        
        // 应用自定义渲染器类到第一列

        frame.add(new JScrollPane(table));
        frame.pack();
        frame.setVisible(true);
    }
}
