A step-by-step walkthrough of combining tables in Power Query using merge and append operations. Covers all six join types (inner, left outer, right outer, full outer, left anti, right anti) with practical examples using a sales dataset and a manually created categories lookup table. Also explains when to use append vs merge, how to handle duplicates after appending, and best practices for final housekeeping including renaming tables/columns and reordering columns for clarity.
