POWER BI:执行CSV联合时聚合的记录总数(序号)

我有40-50个不同城市的csv文件。我想展示一下 记录数量 通过城市和标签过滤时间。

1. 's.no'被聚合并显示记录的总和(我不明白为什么它显示总和,在执行union时不应该是单独的记录编号吗?)也就是说,即使个别文件的序号为1-50,最终表格也应显示序号为1-2500。但事实并非如此。

下图显示了查询编辑器中的数据。

此图显示“数据表视图”中包含聚合和的表

如我们所见, S.NO 显示为聚合。

更新:

从高级编辑器粘贴查询:

let
    Source = Folder.Files("C:\Users\Desktop\data collection\twitter_new_count"),
    #"Filtered Hidden Files1" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from twitter_new_count", each #"Transform File from twitter_new_count"([Content])),
    #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from twitter_new_count"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from twitter_new_count", Table.ColumnNames(#"Transform File from twitter_new_count"(#"Sample File"))),
