Generate Desired Table based on 2 tables

Hi 1320Data ,

Try the following code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTUByIjAyNDJR0lQwMgADPMLJRidaKVjPXBckYociamYDlTfVNMOTMDsJwhmj4jmJmxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, EmpId = _t, Hours = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"EmpId", Int64.Type}, {"Hours", Int64.Type}}),
    #"Sorted Rows" = Table.Sort(#"Changed Type",{{"EmpId", Order.Ascending}, {"Date", Order.Ascending}}),
    #"Added Index" = Table.AddIndexColumn(#"Sorted Rows", "Index", 0, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each try if [EmpId] = #"Added Index" [EmpId] {[Index] + 1} then  #"Added Index" [Date] {[Index] + 1} else null otherwise null),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each try {0.. Duration.Days([Custom] - [Date] ) } otherwise null),
    #"Expanded Custom.1" = Table.ExpandListColumn(#"Added Custom1", "Custom.1"),
    #"Added Custom2" = Table.AddColumn(#"Expanded Custom.1", "Custom.2", each try [Date] + #duration([Custom.1],0,0,0) otherwise [Date]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"Index", "Custom", "Custom.1", "Date"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom.2", "Date"}}),
    #"Sorted Rows1" = Table.Sort(#"Renamed Columns",{{"Date", Order.Ascending}})
in
    #"Sorted Rows1"

Thank you. I did the same by creating index column and self join the table. It worked.
