Observações
Use esta propriedade para controlar programaticamente uma coleção de TableCell objetos que representam as células de uma linha do Table controlo. Pode adicionar, inserir ou remover programaticamente um TableCell objeto da coleção.
Note
Esta propriedade só é usada quando se construem Table controlos programáticos. No momento do design, esta propriedade é definida declarando TableCell objetos.
