excel - 如何在Excel中对列表进行分组？

Question

我有一个 Excel 中的列表列表。第一列中有一些规范(姓名、年龄、国家/地区等)，第二列中有一些值。我不想一遍又一遍地重复相同的规范。我想在图片中展示什么。我尝试了 =VLOOKUP() 但它不能完美工作，因为列表不包含相同的规范。我怎样才能实现这个目标？

Answer 1

VBA 宏可以生成结果，以及第一列结果的参数列表。

要输入此宏(子)，alt-F11 打开 Visual Basic 编辑器。确保您的项目在“项目资源管理器”窗口中突出显示。然后，从顶部菜单中选择插入/模块并将下面的代码粘贴到打开的窗口中。

请务必按照宏中注释中的说明设置引用

要使用此宏(子)，alt-F8 打开宏对话框。按名称选择宏，然后运行。

该宏生成列表，参数列表位于第一列。如果更可取的话，可以很容易地将其重写为将参数列表放在第一行。

编辑:修改宏以反射(reflect)“真实数据”

请注意:您需要为结果添加第二个工作表。我将其命名为“Sheet2”

编辑2:此宏是上述宏的修改，它以相反的方向列出结果。它可能更有用。
