Java:你如何设置Swing组件的样式？

UIManager.put("swing.boldMetal", Boolean.FALSE);
UIManager.put("Button.background", Color.RED);
UIManager.put("Button.foreground", Color.WHITE);
UIManager.put("Button.font", new Font("Arial", Font.PLAIN, 12));

public class CustomButtonUI extends BasicButtonUI {
    @Override
    protected void paintButtonPressed(Graphics g, AbstractButton b) {
        // 自定义按钮按下时的外观
    }
}

SwingUtilities.updateComponentTreeUI(button);
button.setUI(new CustomButtonUI());

public class CustomButtonRenderer extends JButton implements TableCellRenderer {
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        // 自定义渲染器的实现
    }
}

table.getColumn("buttonColumn").setCellRenderer(new CustomButtonRenderer());
