删除一个单元格中的重复文本
Remove duplicate texts in one cell
我目前正在塑造我的数据。我有一个名为 "Centro" 的专栏。但是，仅一个单元格中就有如此多的重复文本。如何删除重复的文本并只显示不同的文本？有人可以帮忙吗？谢谢！！
这是我的代码：
let
Source = Etapa_2_Caricam,
#"Grouped Rows" = Table.Group(Source, {"Material"}, {{"mynewtable", each _, type table [Material=number, Num Form=text, Created on=date, FechaCreac=date, Initiator=text, Texto tarea=text]}}),
#"Added Custom" = Table.AddColumn(#"Grouped Rows", "NoForm", each Table.Column([mynewtable],"Num Form")),
#"Extracted Values" = Table.TransformColumns(#"Added Custom", {"NoForm", each Text.Combine(List.Transform(_, Text.From), ", "), type text}),
#"Added Custom1" = Table.AddColumn(#"Extracted Values", "Iniciador", each Table.Column([mynewtable],"Initiator")),
#"Extracted Values1" = Table.TransformColumns(#"Added Custom1", {"Iniciador", each Text.Combine(List.Transform(_, Text.From), ", "), type text}),
#"Extracted Text Before Delimiter" = Table.TransformColumns(#"Extracted Values1", {{"Iniciador", each Text.BeforeDelimiter(_, ", "), type text}}),
#"Added Custom2" = Table.AddColumn(#"Extracted Text Before Delimiter", "FechaInicio", each Table.Column([mynewtable],"Created on")),
#"Extracted Values2" = Table.TransformColumns(#"Added Custom2", {"FechaInicio", each Text.Combine(List.Transform(_, Text.From), ", "), type text}),
#"Extracted Text Before Delimiter1" = Table.TransformColumns(#"Extracted Values2", {{"FechaInicio", each Text.BeforeDelimiter(_, ", "), type text}}),
#"Added Custom3" = Table.AddColumn(#"Extracted Text Before Delimiter1", "FechaFinalTarea", each let dates = Table.Column([mynewtable],"FechaCreac") in [min = List.Min(dates), max = List.Max(dates)]),
expanded = Table.ExpandRecordColumn(#"Added Custom3", "FechaFinalTarea", {"min", "max"}),
#"Changed Type" = Table.TransformColumnTypes(expanded,{{"min", type date}, {"max", type date}, {"FechaInicio", type date}}),
#"Added Custom4" = Table.AddColumn(#"Changed Type", "TextoTarea", each Table.Column([mynewtable],"Texto tarea")),

#"Changed Type4" = Table.TransformColumnTypes(#"Added Custom5",{{"FechaInicio", type date}}),

#"Reordered Columns" = Table.ReorderColumns(#"Removed Columns1",{"Material", "mynewtable", "NoForm", "Iniciador", "FechaInicio", "min", "max", "TextoTarea"}),

#"Changed Type6" = Table.TransformColumnTypes(#"Reordered Columns1",{{"FechaFinal", type date}}),
#"Removed Columns2" = Table.RemoveColumns(#"Changed Type6",{"max.1", "max.2", "max.3"}),
#"Changed Type7" = Table.TransformColumnTypes(#"Removed Columns2",{{"FechaFinal", type text}, {"FechaInicio", type text}}),
#"Added Custom7" = Table.AddColumn(#"Changed Type7", "Table", each Table.Column([mynewtable],"NoMatAnt")),
#"Extracted Values4" = Table.TransformColumns(#"Added Custom7", {"Table", each Text.Combine(List.Transform(_, Text.From), ", "), type text}),
#"Inserted Text Before Delimiter" = Table.AddColumn(#"Extracted Values4", "Text Before Delimiter", each Text.BeforeDelimiter([Table], ", "), type text),
#"Removed Columns3" = Table.RemoveColumns(#"Inserted Text Before Delimiter",{"Text Before Delimiter"}),
#"Extracted Text Before Delimiter2" = Table.TransformColumns(#"Removed Columns3", {{"Table", each Text.BeforeDelimiter(_, ", "), type text}}),
#"Duplicated Column" = Table.DuplicateColumn(#"Extracted Text Before Delimiter2", "Table", "Table - Copy"),
#"Replaced Value" = Table.ReplaceValue(#"Duplicated Column","CR","",Replacer.ReplaceText,{"Table - Copy"}),
#"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","DO","",Replacer.ReplaceText,{"Table - Copy"}),
#"Replaced Value2" = Table.ReplaceValue(#"Replaced Value1","GT","",Replacer.ReplaceText,{"Table - Copy"}),
#"Replaced Value3" = Table.ReplaceValue(#"Replaced Value2","PR","",Replacer.ReplaceText,{"Table - Copy"}),
#"Renamed Columns1" = Table.RenameColumns(#"Replaced Value3",{{"Table - Copy", "No.FormAnt"}, {"Table", "No.MatAnt"}}),
#"Trimmed Text" = Table.TransformColumns(#"Renamed Columns1",{{"TextoTarea", Text.Trim, type text}}),
#"Added Custom8" = Table.AddColumn(#"Trimmed Text", "Centro", each Table.Column([mynewtable],"Ce")),
#"Extracted Values5" = Table.TransformColumns(#"Added Custom8", {"Centro", each Text.Combine(List.Transform(_, Text.From), ", "), type text})

#"Extracted Values5"
最简单的方法是将逗号分隔值（Centro 字段）拆分为不同的行，然后删除重复项。然后您可以再次将它们分组以获得逗号分隔值。为了演示，我创建了一个 table，其中包含两个字段：PrimaryKey 和 Centro。然后我使用以下步骤获得所需的输出：
来源信息：
= Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUrUSdJJUorViVYyAvKSdVJ0knWSlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)),
let _t = ((type text) meta [Serialized.Text = true]) in type table [PrimaryKey = _t, Centro = _t])
按分隔符拆分列（您可以通过在转换选项卡中选择 "Split Column - By Delimiter" 选项来执行此操作，您必须在选择此选项之前选择 Centro 字段）：
= Table.ExpandListColumn(Table.TransformColumns(Source, {{"Centro", Splitter.SplitTextByDelimiter(",")}}), "Centro")
删除重复项（您可以通过从“主页”选项卡中选择 "Remove Rows - Remove Duplicates" 来执行此操作，请确保在选择此选项之前选择所有列）：
= Table.Distinct(#"Split Column by Delimiter")
分组行（您可以通过在转换选项卡中选择 "Group By" 选项来执行此操作，但您必须稍微编辑查询才能使用定界符聚合）：
= Table.Group(#"Removed Duplicates", {"PrimaryKey"}, {{"Centro_New", each Text.Combine([Centro],","), type text}})
这应该会为您提供所需的输出。希望这有帮助。
编辑：您可以将所有这些合并为一个步骤并使用以下公式：
= Table.Group(Table.Distinct(Table.ExpandListColumn(Table.TransformColumns(Source, {{"Centro", Splitter.SplitTextByDelimiter(",")}}), "Centro")),{"PrimaryKey"}, {{"Centro_New", each Text.Combine([Centro],","), type text}})
