    Hi TuckRhodes ,

    The most common way to do this is to create measures for each column similar to the one below and then bind them to the field parameters:

    Column 1 = 
    VAR __num_null = CALCULATE(COUNTROWS('Table1'),ISBLANK('Table1'[Column1]))
    VAR __num_rows = COUNTROWS('Table1')
    RETURN DIVIDE(__num_null,__num_rows) + 0

    Best Regards,
    Gao
