Answer:
Hollowed or a convex surface, to correct the illusion of sagging in unsupported horizontal lines. The term camber refers to the slight upward arch or curvature of a horizontal surface, particularly on tables, desks, or other flat-topped furniture. Camber is often applied to tabletops to compensate for potential sagging or warping over time, ensuring that the surface remains level. It helps prevent the middle of the table from sinking lower than the edges, allowing objects to be placed on the surface without wobbling or tipping. Camber is achieved by shaping or sanding the underside of the tabletop to create the desired curve.
