Excel VBA：对另一个工作表中多个工作表中的相同列求和（概述）

我是VBA新手，希望快速学习：）

我有6张Excel表格（1-6个月），数据相同（如表所示），但行数不同

我想创建一个以月（1-6）为行、以卷和储量为列的表

还有，有没有一种方法可以让我编写一个代码，根据储量（F列）列出前三大客户群，并给出相应的数量（E列）——比如sumif（），但使用vba

---

我已经研究了好几天，没有发现太多…我很高兴能得到任何帮助！非常感谢：）

这就是使用adodb对象的方式。只需添加3张纸并运行它

数据表作为获取top3的临时表

非常感谢你！！但是，excel给了我一条关于

Rs的错误消息。打开strSQL，strConn

我需要下载什么吗？谢谢：）@Rome，有什么错误消息。
