Shape, height, and function
Tables come in a wide variety of materials, shapes, and heights, that depends on their origin, style, and intended use. All tables are composed of a flat surface and a base with one or more supports, or legs. A table with a single, central foot is a pedestal table. Tables can be freestanding or designed for placement against a wall (a console table). Table tops can be in virtually any shape, although rectangular, square, round (e.g., the round table), and oval tops are the most frequent. Long tables often have extra legs for support. Others have higher surfaces for personal use while either standing or sitting on a tall stool.
Many tables have tops that can be adjusted to change their position, shape or size, either with foldable extensions or sliding parts that can alter the shape of the top. Some tables are entirely foldable for easy transportation, e.g., camping. Small tables in trains and aircraft may be fixed or foldable, although many are simply convenient shelves rather than tables.
