To create date table for the week based on date selected from slicer

Hi kamalmsharma,

I hope you mean the table visual rather than the calculated table, which doesn't respond to the slicer. 

Please download a demo from the attachment. 

1. Create a slicer table without any relationship to other tables.

2. Create two measures.

thisWeek =
VAR selectedDate =
    SELECTEDVALUE ( 'SlicerTable'[Date] )
RETURN
    IF (
        ISBLANK ( selectedDate ),
        BLANK (),
        IF ( WEEKNUM ( MIN ( 'Table'[Date] ) ) = WEEKNUM ( selectedDate ), 1, BLANK () )
    )

previousWeek =
VAR selectedDate =
    SELECTEDVALUE ( 'SlicerTable'[Date] )
RETURN
    IF (
        ISBLANK ( selectedDate ),
        BLANK (),
        IF (
            WEEKNUM ( MIN ( 'Table'[Date] ) )
                = WEEKNUM ( selectedDate ) - 1,
            1,
            BLANK ()
        )
    )

3. Either adding the measures in the table or putting in the Visual Level Filter.

Best Regards,
