Remarks
Use this class to programmatically manage a collection of TableCell objects that make up a row in a Table control. This class is commonly used to add or remove cells from a row in a Table control. .gif) Note |
|---|
A Table control contains a Rows collection that represents a collection of TableRow objects. Each TableRow represents an individual row in the table and contains a Cells collection that represents a collection of TableCell objects. These TableCell objects represent the individual cells in the table. To get an individual cell, you must first get a TableRow from the Rows collection of a Table control. You can then get a TableCell from the Cells collection of the TableRow. |
Examples
The following example demonstrates how to programmatically fill a Table control. TableCell objects, which represent individual cells, are added to TableRow objects, which represent the individual rows, through the Cells property.

Notes
Utilisez cette classe pour manager par programme une collection d'objets TableCell formant une ligne dans un contrôle Table. Cette classe est généralement utilisée pour ajouter des cellules à une ligne d'un contrôle Table ou en supprimer. | Remarque |
|---|
Un contrôle Table contient une collection Rows représentant une collection d'objets TableRow. Chaque TableRow représente une ligne individuelle dans le tableau et contient une collection Cells qui représente une collection d'objets TableCell. Ces objets TableCell représentent les cellules individuelles du tableau. Pour obtenir une cellule individuelle, commencez par obtenir un objet TableRow à partir de la collection Rows d'un contrôle Table. Vous pouvez ensuite obtenir un objet TableCell à partir de la collection Cells de l'objet TableRow. |
Exemples
L'exemple suivant montre comment remplir un contrôle Table par programmation. Les objets TableCell qui représentent des cellules individuelles sont ajoutés aux objets TableRow, qui représentent des lignes individuelles via la propriété Cells.
