a type of thick cloth made of wool that is usually green, used especially for covering card tables and billiard, snooker or pool tables 台面呢（通常绿色，尤用作牌桌、台球台面的衬垫） Word Originlate 16th cent.: from French baies, feminine plural of bai ‘chestnut-coloured’, treated as a singular noun, from Latin badius. The name is presumably from the original colour of the cloth, although several colours are recorded.
