Hi, @Anonymous 

It’s my pleasure to answer for you.

According to your description,I think create two measure in card to calculate the desired result.

Like this:

count1 = COUNTROWS(Table1)

count2 = COUNTROWS(INTERSECT(Table2,Table1))

Here is my sample .pbix file.Hope it helps.

If it doesn’t solve your problem, please feel free to ask me.

Hi, @Anonymous 

If there are more than two columns in the table.

You can try this:

count2 =
COUNTROWS (
    INTERSECT (
        SELECTCOLUMNS ( Table2, "name", [product_name], "id", [ID] ),
        SELECTCOLUMNS ( Table1, "name", [product_name], "id", [ID] )
    )
)

For maximum flexibility you'll want to let the data model do the work for you. Meaning you would need to define some sort of relationship between the tables, and then decide on the filter direction (which table impacts the other). This works ok-ish even if the values are not unique in the "dimension"  table but it would works better if you had a Products reference table that has unique values.
