What is Table: Definition and 925 Discussions

A table is an item of furniture with a flat top and one or more legs, used as a surface for working at, eating from or on which to place things. Some common types of table are the dining room table, which is used for seated persons to eat meals; the coffee table, which is a low table used in living rooms to display items or serve refreshments; and the bedside table, which is used to place an alarm clock and a lamp. There are also a range of specialized types of tables, such as drafting tables, used for doing architectural drawings, and sewing tables.
Common design elements include:

top surfaces of various shapes, including rectangular, square, rounded, semi-circular or oval
legs arranged in two or more similar pairs. It usually has four legs. However, some tables have three legs, use a single heavy pedestal, or are attached to a wall.
several geometries of folding table that can be collapsed into a smaller volume (e.g., a TV tray, which is a portable, folding table on a stand)
heights ranging up and down from the most common 18–30 inches (46–76 cm) range, often reflecting the height of chairs or bar stools used as seating for people making use of a table, as for eating or performing various manipulations of objects resting on a table
a huge range of sizes, from small bedside tables to large dining room tables and huge conference room tables
presence or absence of drawers, shelves or other areas for storing items
expansion of the table surface by insertion of leaves or locking hinged drop leaf sections into a horizontal position (this is particularly common for dining tables)
