这对JTable来说并不难！事实上，它非常容易！

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

这是一个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) {/***/}
    });
