向 Power Query 条件语句添加多个步骤

Question

我有一个有效的单步条件语句

    BlanksToNull = Table.ReplaceValue(#"Trimmed Text","",null,Replacer.ReplaceValue,Table.ColumnNames(#"Trimmed Text")),
    newMergedHeader = Excel.CurrentWorkbook(){[Name="newheader"]}[Content]{0}[Column1],
    #"Merged Columns" = 
     if newMergedHeader <> null then 
      Table.CombineColumns(BlanksToNull,mergeHeaders[List Of Headers For Concatenation], each Combiner.CombineTextByDelimiter("|", QuoteStyle.None)(List.RemoveNulls(_)),"Merged"),
    else 
        BlanksToNull

 in  
  if newMergedHeader <> null then     
     #"Merged Columns"
  else  
     BlanksToNull

但是如果newMergedHeader <> null我也想加上这个 #"Renamed Columns" = Table.RenameColumns(#"Merged Columns",{{"Merged",newMergedHeader}})

有没有办法将它添加到现有的 If 语句中？还是我需要再写一个 If 语句？

我试过了

#"Merged Columns" = 
     if newMergedHeader <> null then 
      Table.CombineColumns(BlanksToNull,mergeHeaders[List Of Headers For Concatenation], each Combiner.CombineTextByDelimiter("|", QuoteStyle.None)(List.RemoveNulls(_)),"Merged"),
      #"Renamed Columns" = Table.RenameColumns(#"Merged Columns",{{"Merged",newMergedHeader}})
    else 
        BlanksToNull

但这不起作用

谢谢

眼球，看起来你多了一个逗号 Merged"),

如果你删除它并合并你的陈述，我认为你可以做到

#"Merged Columns" = 
 if newMergedHeader <> null then 
    Table.RenameColumns(
          Table.CombineColumns(BlanksToNull,mergeHeaders[List Of Headers For Concatenation], each Combiner.CombineTextByDelimiter("|", QuoteStyle.None)(List.RemoveNulls(_)),"Merged")
    ,{{"Merged",newMergedHeader}})
else BlanksToNull

但我不清楚为什么你需要 in 之后的整个尾端而不是仅仅替换

in  
  if newMergedHeader <> null then     
    #"Merged Columns"
  else  
     BlanksToNull

与

in  #"Merged Columns"

因为你已经完成了所有的工作
