Merge Multiple Tables in Power BI: In real time, your data is in a normalized format, but in some situations, you may need the data denormalized. In this situation, you can join those tables with a query editor. Let me show you how to combine multiple tables in Power BI with an example.

Click on the table in any row to display the information for the respective table.
