here is a workaround for you create two columns in each table

Column = "Table1"
Column = "Table2"

Then combine two tables

Table = UNION(Table1,Table2)

Then create two measures for price

price1 =
MAXX ( FILTER ( 'Table', 'Table'[Column] = "Table1" ), 'Table'[Price] )

price2 =
MAXX ( FILTER ( 'Table', 'Table'[Column] = "Table2" ), 'Table'[Price] )
