Concatenate two data from different tables without reference

arvindarvind24 , crossjoin

new table = Crossjoin(Table1, Table2)

or

new table = addcolumns(Crossjoin(Table1, Table2) , "Concat", [Style No] & ", " & [Region]) 

Hi arvindarvind24 
Here is a sample file with the solution https://we.tl/t-IHBj2FTgwN

Concatenated Table = 
SELECTCOLUMNS (
    GENERATE (
        Table1,
        ADDCOLUMNS ( 
            Table2,
            "@Concatenate", Table1[Style No.] & "," & Table2[Region]
        )
    ),
    "Concatenate", [@Concatenate]
)
