Dynamic Group By Table.

Hi JaySharma ,

You can follow the steps below to get it, please check if that is what you want.

1. Create a dimension table using "Enter data" method

2. Create the measures as below

Bins = 
    SWITCH (
        SELECTEDVALUE ( 'Bins'[Index] ),
        0, "0-" & [NW-low],
        1,
            [NW-low] & "-" & [NW-high],
        2,
            [NW-high] & "-" & 10000000
    )

Average NW = 
VAR _len1 =
    SEARCH ( "-", [Bins], 1, 0 )
VAR _minnw =
    VALUE ( MID ( [Bins], 1, _len1 - 1 ) )
VAR _maxnw =
    VALUE ( MID ( [Bins], _len1 + 1, LEN ( [Bins] ) - _len1 ) )
RETURN
    CALCULATE (
        AVERAGE ( 'Table'[Net Worth] ),
        FILTER ( 'Table', 'Table'[Net Worth] >= _minnw && 'Table'[Net Worth] <= _maxnw )
    )

Count Index = 
VAR _len1 =
    SEARCH ( "-", [Bins], 1, 0 )
VAR _minnw =
    VALUE ( MID ( [Bins], 1, _len1 - 1 ) )
VAR _maxnw =
    VALUE ( MID ( [Bins], _len1 + 1, LEN ( [Bins] ) - _len1 ) )
RETURN
    CALCULATE (
        COUNT ( 'Table'[Index] ),
        FILTER ( 'Table', 'Table'[Net Worth] >= _minnw && 'Table'[Net Worth] <= _maxnw )
    )

Count Citizen = 
VAR _len1 =
    SEARCH ( "-", [Bins], 1, 0 )
VAR _minnw =
    VALUE ( MID ( [Bins], 1, _len1 - 1 ) )
VAR _maxnw =
    VALUE ( MID ( [Bins], _len1 + 1, LEN ( [Bins] ) - _len1 ) )
RETURN
    CALCULATE (
        SUM ( 'Table'[Citizen] ),
        FILTER ( 'Table', 'Table'[Net Worth] >= _minnw && 'Table'[Net Worth] <= _maxnw )
    )

3. Create a table visual which need to include the field [Index] of dimension table 'Bins'
