在 Power Query 中添加追加列

Question

我有以下数据集：

我想将 6003.1 和 6003.2 部分加在一起，所以我只有 6003，我的数据集如下所示：

lookup                          criterion   s[m]    Ns[MN]      My[MNm]     Mz[MNm]     Vy[MN]      Vz[MN]      Mt[MNm]     part

我认为这与索引行和旋转我的列以及之后的 unpvivot 有关，但我最终得到了一大堆空行，如下所示：

所以如果这确实是正确的方法，我如何将所有这些空行移动到同一行？

这是我目前的代码：

let
    Source = Append1,
    #"Added Index" = Table.AddIndexColumn(Source, "Index", 1, 1),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Added Index", {"lookup", "criterion", "s[m]", "part", "Index"}, "Attribute", "Value"),
    #"Pivoted Column" = Table.Pivot(#"Unpivoted Columns", List.Distinct(#"Unpivoted Columns"[part]), "part", "Value", List.Sum)
in
    #"Pivoted Column"

非常感谢

Answer 1

首先，确定主要部件号 - 从您的示例数据来看，这看起来我们只是将部件号向下舍入为整数值。

然后您可以简单地按 lookup、criterion 和 part 分组，并对值列求和：

let
    Source = Append1,
    #"Identify Part" = Table.TransformColumns(Source,{{"part", Number.RoundDown, Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Identify Part", {"lookup", "criterion", "part"}, {{"s[m]", each List.Sum([#"s[m]"]), type number}, {"Ns[MN]", each List.Sum([#"Ns[MN]"]), type number}, {"My[MNm]", each List.Sum([#"My[MNm]"]), type number}, {"Mz[MNm]", each List.Sum([#"Mz[MNm]"]), type number}, {"Vy[MN]", each List.Sum([#"Vy[MN]"]), type number}, {"Vz[MN]", each List.Sum([#"Vz[MN]"]), type number}, {"Mt[MNm]", each List.Sum([#"Mt[MNm]"]), type number}}),
    #"Reordered Columns" = Table.ReorderColumns(#"Grouped Rows",{"lookup", "criterion", "s[m]", "Ns[MN]", "My[MNm]", "Mz[MNm]", "Vy[MN]", "Vz[MN]", "Mt[MNm]", "part"})
in
    #"Reordered Columns"
