Cross table (100, 100', 100") for a woodworking machine, in particular for a sliding table saw, comprising: - a cross table frame (102, 104, 170, 171), - a horizontally lying first workpiece support surface (110a, 110b), - a stop rail fastened to the cross table frame above the first workpiece support surface, with ∘ a first vertically standing workpiece stop surface on a first side of the stop rail, which is arranged such that a plate-shaped workpiece resting on the first workpiece support surface in a first abutment region arranged horizontally in front of the stop rail can be placed with a side edge against the first workpiece stop surface, ∘ a second vertically standing workpiece stop surface on a second side of the stop rail opposite the first side, the second workpiece stop surface being arranged in such a way that a plate-shaped workpiece resting on the first workpiece support surface in a second support region arranged horizontally behind the stop rail can be placed with a side edge against the second workpiece stop surface, characterized in that - the first workpiece support surface is formed by a support surface (110a, 110b) of a support beam (130, 132), and - the support beam is arranged reciprocally movable relative to the cross table frame so that the distance of the front support beam end and the rear support beam end to the stop rail is variable, i.e. can be increased and decreased. - a cross table frame (102, 104, 170, 171), - a horizontally lying first workpiece support surface (110a, 110b), - a stop rail fastened to the cross table frame above the first workpiece support surface, with ∘ a first vertically standing workpiece stop surface on a first side of the stop rail, which is arranged such that a plate-shaped workpiece resting on the first workpiece support surface in a first abutment region arranged horizontally in front of the stop rail can be placed with a side edge against the first workpiece stop surface, ∘ a second vertically standing workpiece stop surface on a second side of the stop rail opposite the first side, the second workpiece stop surface being arranged in such a way that a plate-shaped workpiece resting on the first workpiece support surface in a second support region arranged horizontally behind the stop rail can be placed with a side edge against the second workpiece stop surface, ∘ a first vertically standing workpiece stop surface on a first side of the stop rail, which is arranged such that a plate-shaped workpiece resting on the first workpiece support surface in a first abutment region arranged horizontally in front of the stop rail can be placed with a side edge against the first workpiece stop surface, ∘ a second vertically standing workpiece stop surface on a second side of the stop rail opposite the first side, the second workpiece stop surface being arranged in such a way that a plate-shaped workpiece resting on the first workpiece support surface in a second support region arranged horizontally behind the stop rail can be placed with a side edge against the second workpiece stop surface, - the first workpiece support surface is formed by a support surface (110a, 110b) of a support beam (130, 132), and - the support beam is arranged reciprocally movable relative to the cross table frame so that the distance of the front support beam end and the rear support beam end to the stop rail is variable, i.e. can be increased and decreased.
