HtmlTableCellCollection.Insert メソッド
アセンブリ: System.Web (system.web.dll 内)

Dim instance As HtmlTableCellCollection Dim index As Integer Dim cell As HtmlTableCell instance.Insert(index, cell)

Insert メソッドを使用して、指定した HtmlTableCell オブジェクトを、HtmlTableCellCollection コレクション内の指定したインデックス位置に追加します。単に HtmlTableCell オブジェクトをコレクションの末尾に追加する場合は Add メソッドを使用します。

Insert メソッドを使用して、HtmlTableCellCollection コレクションに HtmlTableCell オブジェクトが表すテーブルのセルを動的に挿入する方法を次のコード例に示します。
