範例
下列範例示範如何以程式設計方式將資料列加入資料表加TableRow為代表資料表的資料列的物件Table透過控制Rows屬性。The following example demonstrates how to programmatically add rows to a table by adding TableRow objects, which represent the rows of the table, to the Table control through the Rows property.

備註
使用這個類別來以程式設計方式管理集合TableRow物件。Use this class to programmatically manage a collection of TableRow objects. 這個類別常用來新增或移除資料列從Table控制項。This class is commonly used to add or remove rows from a Table control.
注意
ATable控制項包含Rows集合，表示集合TableRow物件。A Table control contains a Rows collection that represents a collection of TableRow objects. 每個TableRow代表資料表中的個別資料列，並包含Cells集合，表示集合TableCell物件。Each TableRow represents an individual row in the table and contains a Cells collection that represents a collection of TableCell objects. 這些TableCell物件代表資料表中的個別儲存格。These TableCell objects represent the individual cells in the table. 若要取得個別資料格，您必須先取得TableRow從Rows的集合Table控制項。To get an individual cell, you must first get a TableRow from the Rows collection of a Table control. 您可以取得TableCell從Cells的集合TableRow。You can then get a TableCell from the Cells collection of the TableRow.
