Excel中有合并单元格时使用ShiftRows方法报“索引超出范围”错误的解决方法

方法名：ShiftRows(int startRow, int endRow, int moveNum, bool CopyRowHeight, bool resetRowHeight)

说明：移动行

参数：startRow-待移动行范围起始索引

          endRow-待移动行范围截止索引

          moveNum-要移动的行数

          CopyRowHeight-是否复制行高

          resetRowHeight-行移动后，源行高是否还原为excel默认高度

注：此方法存在Bug，当被移动的行中有合并单元格时会报“索引超出范围”的错误

不完美解决办法：重写一个移动行方法MoveRows，但是不能有行合并的情况
