Hi! mohanpal
You can use the function fill down in query editor.
Select the column and use the fill down option.

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjEyUNJRMlSK1YGxjSBsYyMg2xiJbQJhm5oC2aYQtoUZkG0GZVsC2eZKsbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Col A" = _t, Index = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Col A", Int64.Type}, {"Index", Int64.Type}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "New Col", each if [Index]=1 then [Col A] else null, type number), #"Filled Down" = Table.FillDown(#"Added Custom",{"New Col"}) in #"Filled Down"-------------------------------------------------------------------------------------------------------

NewStep=let val=PreviousStepName{[Index=1]}?[ColA]? in Table.AddColumn(PreviousStepName,"NewCol",each val)
