Creating a Dynamic Matrix Based on Column Names in Every Table

Hi, taylorb 

According to your description, I guess you want to get a table that displays the [CustomerSource] column in the five tables, and the value should be the user who views this report. I think you can not achieve this in a simple DAX, you can create measures for each table to get the expected result, you can take a look at my steps:

1. Create the five measures in five tables (one by one):

Table1 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table1',[CustomerSource]=USERPRINCIPALNAME()))

Table2 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table2',[CustomerSource]=USERPRINCIPALNAME()))

Table3 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table3',[CustomerSource]=USERPRINCIPALNAME()))

Table4 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table4',[CustomerSource]=USERPRINCIPALNAME()))

Table5 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table5',[CustomerSource]=USERPRINCIPALNAME()))

2. Create a table chart and place them into it, and view as a username, you can get what you want, like this:

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
