Append queries adds NULL
In Power Query, add a custom column. Just put the name of the table2 query after the '='
This will give you a row like
col1 col2 custom
42739 557... Table
Expand the custom column using the header icon.
You are now 2/3 of the way there.
Add another custom column with the name of the third query, and expand that too
It sounds like your doing an Append, not a Merge. Can you verify you are doing a merget, and include what join kind you are using.
