dynamically changing the column display based on slicer selection..

AkhilAshok - Thanks for the inputs. I see two more issues with the logic you provided.

When user selects Prod2018 in the slicer, the table is only showing the values in one column (Count SelectedYear) instead it has to show values for 2017 in (Count PreviousYear column) and 2018(Count SelectedYear column). Similarly when user selects Prod2017 from slicer it has to show 2017 and 2016 year values in the columns shown in the table.

Please see the picture below, it is only showing the values in CountSelectedYear and not displaying the previous year values in the countPreviousYear column.

The other issue is it is showing the count individually for the same products as shown in the above picture(Laptop,Mobile). I want to summarize and show the count for each product as shown in the below image.

The measure i have created to calculate the column "count2018" is as below:

count2018 = CALCULATE(
 COUNTAX(
        FILTER ( 'ProdData', ('ProdData'[Level] = "A1"  || 'ProdData'[Level] = "A2" || 'ProdData'[Level] = "A3") && (ProdData[Model] = "2018")),
        'ProdData'[Level]   
))

Any inputs are much helpful.
