做了一个QTableWidget的数据展示，发现滚动过快，原来是这个原因：
enum QAbstractItemView::ScrollMode
Describes how the scrollbar should behave. When setting the scroll mode to ScrollPerPixel the single step size will adjust automatically unless it was set explicitly using setSingleStep(). The automatic adjustment can be restored by setting the single step size to -1.
