Row wise sum in Matrix..Need help

Hi, Fabric999 

Thanks for the reply from Rupak_bi. You can try the following method to achieve your need.

Step1: Add totals to the original table for the Sales values corresponding to each date

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("fZS9TgMxEITf5epI8f/ZJYQmikSDqE4pEKJAUEHF23N2zs6td8dNTroZ7c14P2dZJn007miU8dNhOr39/K6P15eH9dfM0/WwTAbp2hTdQj0W3SE93eZ7pMfb/IB0m4q+z//4+fWxC2BZAWpYX/UNOoNlFajBKtaBGubASnQheYvT3/v3PkTge6COFPgmqCPyIp1DK16lD6L4QqgjOF5mW9nlnkIiKssBA5VlryFPRQ4Qpyw7D2nKsubJ255KNr4Eoke+AqJrj0kqOk9PdDPgKOvWDjAqA9KAonJAwukTw3ZfZYZKBjcg6HK/kDJAu5YCP+fnp3MmzGmEUHXEiCiqDmMQSNWRPGKpfQXi1GbMkKhq8QpC1SWRuGpTHESrWmyEdFVLiBCw7mRFxtp+eCXmmYUN9Z7tvomwVc/wL6sLLTLXAq1zrv8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Product = _t, Country = _t, Sales = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Product", type text}, {"Country", type text}, {"Sales", Int64.Type}}),
    #"GroupedRows" = Table.Group(#"Changed Type", {"Date", "Product"}, {{"Total Sales", each List.Sum([Sales]), type number}}),
    NewRows1 = Table.TransformColumns(GroupedRows, {{"Total Sales", each _}}),
    NewRows2 = Table.AddColumn(NewRows1, "Country", each "Totals of each month"),
    CombinedTable = Table.Combine({Source, NewRows2}),
    #"Changed Type1" = Table.TransformColumnTypes(CombinedTable,{{"Date", type date}, {"Sales", Int64.Type}, {"Total Sales", Int64.Type}}),
    #"Replaced Value" = Table.ReplaceValue(#"Changed Type1",null,0,Replacer.ReplaceValue,{"Sales"}),
    #"Replaced Value1" = Table.ReplaceValue(#"Replaced Value",null,0,Replacer.ReplaceValue,{"Total Sales"}),
    #"Added Custom" = Table.AddColumn(#"Replaced Value1", "Custom", each [Sales]+[Total Sales]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Sales", "Total Sales"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom", "Sales"}})
in
    #"Renamed Columns"

 Steps 2: Add the new table of country and sort by Index
