使用 JTable 一点也不难!事实上，这非常简单!

...子类 JTable 并覆盖 JTable.preparedRenderer(TableCellRenderer renderer, int row, int column) 。如果行和列数字相同，您可以更改作为显示返回的Component的背景颜色(通常是 JLabel);

下面是突出显示鼠标所在行的示例:

@Override
public Component prepareRenderer(final TableCellRenderer renderer, final int row, final int column) {
    final Component c = super.prepareRenderer(renderer, row, column);
    if (row == this.itsRow) {
        c.setBackground(Color.RED);
    }
    return c;
}

其中 this.itsRow 是由 MouseMotionListener 更新的 int 字段:

this.addMouseMotionListener(new MouseMotionListener() {
        public void mouseMoved(MouseEvent e) {
            SubclassedJTable.this.itsRow = SubclassedJTable.this.rowAtPoint(e.getPoint());
            SubclassedJTable.this.repaint();
        }
        public void mouseDragged(MouseEvent e) {/***/}
    });
