有没有办法为JTable创建渐变背景？

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

public class GradientTableCellRenderer 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);

        if (!isSelected) {
            // 创建渐变背景
            Color startColor = Color.WHITE; // 渐变起始颜色
            Color endColor = Color.LIGHT_GRAY; // 渐变结束颜色
            GradientPaint gradientPaint = new GradientPaint(0, 0, startColor, getWidth(), getHeight(), endColor);
            ((JComponent) component).setOpaque(true);
            ((JComponent) component).setBackground(gradientPaint);
        }

        return component;
    }
}

JTable table = new JTable();
table.getColumnModel().getColumn(columnIndex).setCellRenderer(new GradientTableCellRenderer());
