A table is a large, flat piece of furniture with long legs. You usually sit around a table on chairs and eat dinner. Small tables are often put near sofas so people can put their coffee cups on them. Most tables are made out of wood, with either wood or metal legs. Tables can be round or square.
Table tennis, also called ping pong, is a game where two or four people holding paddles bounce a light, hollow ball across a table with a net in the middle of it. The idea is to only bounce the ball once on each side of the net, and if you miss the ball and can't hit it back, your opponent gets a point.
Most animals have tails - people and apes don't. A tail is just an extension of the animal's backbone. Animals use their tails to communicate - dogs wag their tails when they are happy, cats wave their tails when they are angry and put their tails straight up to say "hello".
Animals like cows and horses use their tails to swat flies away. The kangaroo has a big, heavy tail that it uses to balance itself when it hops.
