範例
下列範例示範如何透過TableRow Rows屬性, 將代表資料表資料列的物件加入至資料表, Table以程式設計方式將資料列新增至資料表。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, 以程式設計方式管理TableRow物件的集合。Use this class to programmatically manage a collection of TableRow objects. 這個類別通常用來加入或移除Table控制項中的資料列。This class is commonly used to add or remove rows from a Table control.
注意
控制項包含代表TableRow物件集合的集合。Rows TableA Table control contains a Rows collection that represents a collection of TableRow objects. 每TableRow個都代表資料表中的個別資料列, Cells並包含代表TableCell物件集合的集合。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資料格。These TableCell objects represent the individual cells in the table. 若要取得個別的資料格, 您必須先TableRow從Table控制項Rows的集合中取得。To get an individual cell, you must first get a TableRow from the Rows collection of a Table control. 然後, 您就可以TableCell從的Cells集合TableRow中取得。You can then get a TableCell from the Cells collection of the TableRow.
