A sorting table with grading rolls supported by end supports and positioned to form a sorting plane. The rolls are rotated in the same direction and configured to create at least one opening between adjacent rolls to permit the pass-through of only the products to be sorted or calibrated. Larger products remain at the surface and are evacuated downstream. The gap between rolls can be modified. Elastic elements are interposed between said end supports and means of actuation for are provided bringing said end supports and the rolls supported by the latter closer together or moving them farther apart, in opposition to the antagonistic action exerted by said elastic elements, to decrease or increase the cross section of the openings, displacements in the opposite direction of said end supports and of the grading rolls being achieved by the action of extension or compression of said elastic elements.
