解决方法

按照以下步骤获得所需的输出-

Spet-1： 复制您当前的数据表并给出适当的名称。您现在可以对这个新表应用必要的转换，并且您的源数据对于其他用途保持不变。让你的数据如下-

第 2 步：转到新表的高级编辑器，并将代码替换为以下代码-

注意：您的表列名称需要如上图所示。

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcsxNLcpMTlTSUXIEYr/8PIXwjMySVKVYHaBcaXFJUWJOJkjWCYiRZNKgmpwwNcENdMZrIBbr4DrRLENzBpquNNzWwQ10wWmgC0WOxK3TGXt4YbEuDbunSQhGkoMKl1VYvEtMRJMUEvjDHk84obiSqkkRfxogPiZxuRC7YbEA",BinaryEncoding.Base64),Compression.Deflate)),let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Area = _t,Client = _t,#"Ethnic Group" = _t]),#"Changed Type" = Table.TransformColumnTypes(Source,{{"Area",type text},{"Client",{"Ethnic Group",type text}}),#"Grouped Rows" = Table.Group(#"Changed Type","Area","Ethnic Group"},{{"Count",each Table.RowCount(_),Int64.Type}}),#"Pivoted Column" = Table.Pivot(#"Grouped Rows",List.Distinct(#"Grouped Rows"[#"Ethnic Group"]),"Ethnic Group","Count",List.Sum),#"Replaced Value" = Table.ReplaceValue(#"Pivoted Column",null,Replacer.ReplaceValue,{"Non White"}),#"Replaced Value1" = Table.ReplaceValue(#"Replaced Value",{"White"}),#"Added Custom" = Table.AddColumn(#"Replaced Value1","Custom",each ([Non White]*100.00)/([Non White]+[White])),#"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom",#"Renamed Columns1" = Table.RenameColumns(#"Changed Type1","% Non White"}}),#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Renamed Columns1","Area"},"Attribute","Value"),#"Renamed Columns2" = Table.RenameColumns(#"Unpivoted Other Columns",{{"Attribute","Ethenic_group"}}),#"Replaced Value2" = Table.ReplaceValue(#"Renamed Columns2","Non White"," Non White",Replacer.ReplaceText,{"Ethenic_group"}),#"Replaced Value3" = Table.ReplaceValue(#"Replaced Value2","White"," White",#"Replaced Value4" = Table.ReplaceValue(#"Replaced Value3","%  Non  White","% Non White",#"Added Custom1" = Table.AddColumn(#"Replaced Value4",each if [Ethenic_group] = "% Non White" then Text.From([Value]) & "%" else Text.From([Value]))
in
    #"Added Custom1"

这是最终的输出-

第 3 步：现在返回报告并在报告中添加指标并配置如下-

第 4 步：点击如下所示的红色方框图标-

最后您将看到以下演示文稿-
