Travailler avec des tableaux dans des PDF tagués

Créer un tableau dans un PDF tagué

Aspose.PDF for .NET permet de créer un tableau dans des documents PDF tagués. Pour travailler avec des tableaux, l’API fournit la classe TableElement. Afin de créer un tableau, vous pouvez utiliser la méthode CreateTableElement() de l’interface ITaggedContent. De plus, vous pouvez utiliser les méthodes CreateTHead(), CreateTBody() et CreateTFoot() de la classe TableElement pour créer respectivement l’en-tête, le corps et le pied de tableau. Pour créer une ligne de tableau, vous pouvez utiliser la méthode CreateTR() de la classe TableRowCollectionElement. Vous pouvez également vérifier si le document PDF créé est conforme à la norme PDF/UA en utilisant la méthode Validate() de la classe Document.

Le code suivant fonctionne également avec la bibliothèque Aspose.PDF.Drawing.

Styliser un élément de tableau

Aspose.PDF for .NET permet de styliser un tableau dans un document PDF tagué. Afin de styliser un tableau, vous pouvez créer un tableau en utilisant la méthode CreateTableElement() de l’interface ITaggedContent et définir le style du tableau en utilisant les propriétés de la classe TableElement. Voici la liste des propriétés que vous pouvez utiliser pour styliser un tableau :

• BackgroundColor.
• Border.
• Alignment.
• CornerStyle.
• Broken.
• ColumnAdjustment.
• ColumnWidths.
• DefaultCellBorder.
• DefaultCellPadding.
• DefaultCellTextState.
• DefaultColumnWidth.
• IsBroken.
• IsBordersIncluded.
• Left.
• Top.
