I think you reversed the case:- Making Rows as I/ps and Columns as O/ps, Rows connected to PORTB and Columns connected to PORTA. In code you wrote, DDRA = 0x00 (i.e. I/P) and DDRB = 0xFF (i.e. O/P). Also, at 4.01 you said that pull-down resistor is connected to each column. I'm not getting it, kindly explain to me if I'm wrong. So with all these points I strongly feel that the case is :- Rows as O/p and columns as i/ps
