There are several different types of tables for different use.
Competition tables usually have a thicker topboard (between 22 and 25 mm) than the regular, recreational tables, and therefore are perfect to be used by clubs who play a lot of matches.
There are also tables for recreation. For indor or outdoor. Most of these outdoor tables can be left outdoor all year long, because of their weather proof toppings.

Most table tennis tables are available with a green or blue top, without extra charge.
