The invention relates to agricultural engineering and is intended for use as a separating working body of a pneumatic sorting table. A deck of a pneumatic table comprises a mesh separating surface with guides for movement of seeds and an air equilibrating grid connected thereto and secured on a frame. The guides for movement of seeds are made in the form of stepped corrugations of separating surface, whose height H is decreasing, and the length L increases with the distance from the place of supply of seed mixture onto the separating surface of deck and approaching the discharge edge of the surface. Use of the invention improves the efficiency of separation of seeds according to the density of particles.
