Abstract: The present disclosure provides a telescopic panel component and a table, relates to the technical field of furniture, and solves the technical problem that the size of a panel component of a table is fixed and cannot be adjusted. The telescopic panel component comprises a frame, a first panel and a second panel, wherein a slideway is provided on the frame, and the second panel is slidably connected with the slideway; the panel component has a retracted state and an unfolded state, and when the second panel slides along the slideway to the side of the first panel under the action of an external force, the first panel is rotatable on the frame; the first panel turns over forward, and the first panel is rotatable below the second panel, so that the panel component is in the retracted state; the first panel turns over reversely, and the first panel is rotatable to the position where the first panel is spliced with the second panel, so that the panel component is in the unfolded state.
