What is Appending Tables?

Appending tables stacks two or more tables with matching columns on top of each other, combining their rows into a single table. It works like a union in SQL and is common when combining monthly files or data pulled from multiple similar sources into one query. Power Query handles column matching automatically when column names align, and flags mismatches when they don't.
