1099g table has 0 while table B has certain amount that I had received while on PFL. please suggest how to fill

You can add the amounts from Box 1 together and then enter them.  If your Table A Box 1 has zero and your Table B Box 1 has a number, then report that number in Table B as Box 1. 

You only need to enter it as one form. For your federal tax return, the Tables do not matter.  Table A is for Unemployment and Table B is for Paid Family Leave.
