Hide tables using a card

[BishwaR]

I have two exact tables A and B.  A filters B but B does not filter B because I disabled the filter on B.

Now the purpose of B is to work as a drillthrough page. 

If I select a row in A it will filter B based on my selection.

Now I want to hide Table B and get visible only when I make a selection in A.

Can I create a measure  if Countrow < 2,"FFFFFF00","White" and use a card to cover the table B

Thanks

@BishwaR , Card background and font all should use this in conditional formatting 

if( isfiltered(Table[A]), "FFFFFF00","White" )

Use in conditional formatting using filed value option. It is based on the column that was expected to be filtred

or use countrows(Table)
