FAQ
When should I use Table.Combine in Power Query?
Use Table.Combine when the transformation should be repeatable every time the data refreshes.
Can I do Table.Combine from the Power Query interface?
Usually yes. The interface creates the M code for many common transformations, and you can adjust it in the formula bar or Advanced Editor.
Should I edit the M code manually?
Edit M manually when the interface cannot express the pattern clearly, or when you need reusable logic, parameters or cleaner step names.
