注釈

コントロールの行のセルを表すオブジェクトのTableCellコレクションをプログラムで制御するには、このプロパティを使用します。 TableUse this property to programmatically control a collection of TableCell objects that represent the cells from a row of the Table control. プログラムを使用して、オブジェクトをTableCellコレクションに追加、挿入、または削除できます。You can programmatically add, insert, or remove a TableCell object from the collection.

注意

このプロパティは、プログラムによっTableてコントロールをビルドする場合にのみ使用されます。This property is only used when building Table controls programmatically. デザイン時に、このプロパティは、オブジェクトのTableCell宣言によって設定されます。At design time, this property is set by declaring TableCell objects.
