排序和分组行

Question

我有一个看起来像这样

ID Event_A Event_B Event_C 
1 01-01 
1 01-02 
1   01-05 
2 01-02 
2     01-03 
3 01-03 
3 01-04 
3   01-06 
3     01-08 

我需要这样的

ID Event_1 Event_2 Event_3 Event_4 
1 A  A  B 
2 A  C 
3 A  A  B  C 

输出

所以基本上有一行每个ID表以及根据时间戳（按时间顺序）列中的所有事件类型。

任何人都可以建议宏如何应该看起来像OR SQL查询来转换原始表？

Answer 1

这里有一个VBA程序重新格式化您的数据：

1. 假定源数据是活动工作表，在A1开始
2. 地方在F1主动片材起始导致 - 调整，以满足您的需求
