How to fuzzy match the dirty data and horizontal display the corresponding table

 Scenario:    

In this scenario, the column [City] in my table has some dirty data with some space and case errors. It's also a mixture of abbreviations and full names of the cities.

I want to find a way to unify the value of the column ‘City’ into the abbreviation of the cities, and merge this abbreviation into the column name of the table to display the table data horizontally with Forecasted Gross and Forecasted Net.

  

The original status of the main table is like below:

Expected result：

Detailed steps： 

  1. Go to power query editor, click on “Enter data” and create a Transformation table like this:
