Remarks
The TableItemStyle class represents the style properties for an element of a control that renders as a TableRow or TableCell. You can control the vertical and horizontal alignment of the contents in an item of the table by setting the HorizontalAlign and VerticalAlign properties, respectively. You can also specify whether the contents of the cell automatically continue on the next line when the end of the cell is reached by setting the Wrap property. This class provides methods that are useful for creating a style for an item in the Table control. You can use the CopyFrom and MergeWith methods to copy or merge the style properties of another TableItemStyle with the instance of the TableItemStyle that the method is called from.
Examples
The following code example creates several rows in a Table control and applies a TableItemStyle object to each row.

Notes
La classe TableItemStyle représente les propriétés de style relatives à un élément d'un contrôle restitué sous forme de TableRow ou de TableCell. Vous pouvez définir les propriétés HorizontalAlign et VerticalAlign pour contrôler respectivement l'alignement vertical et horizontal du contenu d'un élément du tableau. Vous pouvez également définir la propriété Wrap pour spécifier si le contenu de la cellule est automatiquement renvoyé à la ligne suivante lorsque la fin de la cellule est atteinte. Cette classe fournit des méthodes utiles pour créer un style pour un élément du contrôle Table. Vous pouvez utiliser les méthodes CopyFrom et MergeWith afin de copier ou fusionner les propriétés de style d'un autre TableItemStyle avec l'instance de TableItemStyle à partir de laquelle la méthode est appelée.
Exemples
L'exemple de code suivant crée plusieurs lignes dans un contrôle Table et applique un objet TableItemStyle à chaque ligne.
