Комментарии

Это свойство используется для программного управления коллекцией TableCell объектов, представляющих ячейки из строки Table элемента управления.Use this property to programmatically control a collection of TableCell objects that represent the cells from a row of the Table control. Можно программно добавить, вставить или удалить TableCell объект из коллекции.You can programmatically add, insert, or remove a TableCell object from the collection.

Примечание

Это свойство используется только при программном Table построении элементов управления.This property is only used when building Table controls programmatically. Во время разработки это свойство задается путем объявления TableCell объектов.At design time, this property is set by declaring TableCell objects.
