Some cards simply have the number on it ("1"). Some have the number written out in letters ("One"). They are usually written in black and white, perhaps with the word "Table" in front ("Table One").
Yet others include more information, such as the first names of the bridge and groom, the surname, a monogram or initial of the surname, the date of the wedding or event, and any other information you would like to add. Some have various designs, colors or images on it.
