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?

        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
        	Combine

        Copy 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.
