Compare between 2 tables and highlight field changes

If you wish to use a measure (and identify rows missing from either table if so you wish), you can create dimension tables for the fields and set the model like this:

 Then create a measure as follows:

Excluded from = 
VAR T1 = COUNTROWS(EXCEPT(Table1, Table2))
VAR T2 = COUNTROWS(EXCEPT(Table2, Table1))
RETURN
SWITCH(TRUE(),
T1 = 1, "Not in Table 2",
T2 = 1, "Not in Table 1")

Then create a table visual with the fields from the dimension tables and add the measure:
