在作物品种区域试验时，通常会采用随机区组试验设计，特制作了一个可以自动生成随机区组试验的小程序。excel参数界面如下：

参数含义如下：

1、生成新表的名称：程序将新建表格，用于生成随机区组试验。若此处为空，则为系统默认的新建表格名称，若含有名称，则新建表以此名称命名。

2、是否含排区号：若选择“是”，则以“1-1”的形式显示第几排，第几个小区。若选择“否”，则不显示，仅在标题处显示区组名称。

3、区组内品种排列方向：若为“横向”，则表格中在同一行中排列一个区组的不同品种；如选择“纵向”，则表格中在同一列中排列一个区组的不同品种。

4、区组数量：表示需要设置的区组数量，通常为3。

以上图中默认的设置运行代码，显示结果如下：

具体实现代码如下：
