我想通过一个公共变量（“mass”列）对齐多个（6+）数据集（每个数据集 3 列 x 1000 行），其中每个数据集将有几个完全匹配的公共值、许多几乎匹配的公共值（即 635.62417 和 635.62413）和许多唯一值。但我需要根据几乎匹配的值对齐所有 6 个数据集，并维护它们每个相邻（相关）列，包括唯一值。
例如，只有 3 个集合且每个集合只有 2 列，它可能看起来像这样：
因为我需要按公共（质量）和近似公共值（假设它们匹配在 0.0005% 以内）对齐集合，同时保持每个集合的相邻信息列（计数）和不匹配的值......所以它看起来像：
正如我提到的，我需要对齐 6 个相关的 3 列数据集，然后重复约 100 次。因此，手动排序/点击次数越少越好。
我尝试过 Vlookup，但它只返回公共列，并且不支持超过两个数据集（据我所知）。它还需要创建匹配列，这在跨 6 个（3 列）集对齐时会变得难以处理。
我还尝试为每个集合的每一行创建一个数据集标签列（setA、setB、setC..），然后将所有 6+ 个集合连接成一个 6000+ 个值（现在为 4 个）的列集合，按公共变量列（质量）排序，然后编写一个嵌套 if 函数来搜索所有 6 个集合标签（a、b、c...）的 6 个几乎连续的值。但是，该函数太长了，如果一个集合在第 6 个集合的值之前几乎相同的间隔（0.0005%）中包含多个值，它就无法处理。例如，所有 6 个集合可能具有几乎相同的值（在 0.0005% 的间隔内），但一个或多个集合在间隔内有两个值，从而在连接排序列表的间隔内创建 7 个或更多连续值。
保持唯一性并维持公共变量列的序列（顺序）很重要，但一旦我知道我可以对齐，我可能会找到一些解决方法。
这里有一个（csv 列表）更完整/精确的数据集（前 14 行）可以使用。
