【问题描述】：

let Source = Csv.Document(File.Contents("D:\Users\swaip\Downloads\raw_data_metrics.csv"),[Delimiter=",", Columns=9, Encoding=65001, QuoteStyle=QuoteStyle.None]), 
#"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]), #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers","KEY", type text, "VALUE", type number, "MODEL_NAME", type text, "METRIC_GROUP", type text, "COUNTRY", type text, "DATE_TIME", type datetime, "RUN_ID", type text, "ENV", type text, "_METADATA_FILE_NAME", type text), 
#"Filtered Rows" = Table.SelectRows(#"Changed Type", each true), 
#"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", 
latest = List.Max(#"Filtered Rows"[DATE_TIME]) in each Text.StartsWith([METRIC_GROUP], "prediction") and [DATE_TIME] = latest),
#"Filtered Rows2" = Table.SelectRows(#"Filtered Rows", each Text.StartsWith([METRIC_GROUP], "training")) in #"Filtered Rows1"

【参考方案1】：

combined = #"Filtered Rows1" & #"Filtered Rows2",

或

combined = Table.Combine(#"Filtered Rows1",#"Filtered Rows2"),

如果它们具有相似的列结构，则将第二个附加到第一个。
