Merge Tables Without Matching Data
From a Support Ticket system, due to limitations with API calls, I have multiple tables with the same column names but different data. The tables are separated by date ranges.
I need to merge these so I can report on different time periods and trends. In my research, I only see merging options where you have matching data. Any ideas are welcome!

So you have something like:
Table1: col1,col2,col3
Table2: col1,col2,col3
And you want:
col1,col2,col3,col1a,col2a,col3a
Or do you want to Append the tables together?

I'd like to append the tables together.
P.S. - I read your article on how to get your question answered quickly and am providing a link to 2 sample tables with anonymized data.

Hello S0Fr33
add a prefix to every column (example table name) and combine the tables afterwards. I've prepared a very basic code example where you see how this could work
let SourceTableA = #table ( {"COLA","COL2"}, { {"a","c"}, {"b","d"}, {"e","f"} } ), SourceTableB = #table ( {"COLA","COL2"}, { {"a","c"}, {"b","d"}, {"e","f"} } ), NewColumnNamesTableA = List.Transform(Table.ColumnNames(SourceTableA),each "TableA"&_), NewColumnNamesTableB = List.Transform(Table.ColumnNames(SourceTableB),each "TableB"&_), RenameTableA = Table.RenameColumns(SourceTableA,List.Zip({Table.ColumnNames(SourceTableA), NewColumnNamesTableA})), RenameTableB = Table.RenameColumns(SourceTableB,List.Zip({Table.ColumnNames(SourceTableB), NewColumnNamesTableB})), Combine = Table.Combine({RenameTableA, RenameTableB}) in CombineCopy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query.
