我的 Google 电子表格中有上述 table。我想要做的是对重复的阶段进行分组，return 每组阶段的最大日期。

我知道如何通过这样做获得所有单元格的最大日期： =max(arrayformula((B:B=B2)*(C:C)))

但是，我想 return 每个阶段的最大日期。我希望我的 table 如下所示：

Answer 1

尝试使用查询。在D2中输入，将公式复制下来：

=query($A2:$C19,"select B where A='" & A2 &"' and C='" & C2 &"' order by B desc limit 1 ")

Select B 获取日期。其中 A = '" & A2 &"' 限制为单元格 A2 中的值（名称）。 C2= 对 C2 中的单元格值执行相同的操作。它按日期排序。在这种情况下降序。限制 1 有效地获取最大日期，因为它只有 returns 一个值。我希望解释查询。

如何对相似的单元格进行分组并获得这些单元格中的最大值？

How do I group similar cells and get the maximum value among those cells?
