hello dude
So, F=ma
Your block exerts a force of 1kg * 9.8 m/s2 = 9.8 Newtons downward on the table.
Your table exerts a force of 9.8 Newtons upward on the block.
And the net is zero.
Unless, of course, the table is sitting in quicksand, in which case the table may actually exert less than 9.8 newtons upward.
