العمل مع الجداول في ملفات PDF المعلّمة

إنشاء جدول في PDF المعلّم

Aspose.PDF for .NET يتيح إنشاء جدول في مستندات PDF المعلّمة. للعمل مع الجداول، توفر واجهة برمجة التطبيقات TableElement class. لإنشاء جدول، يمكنك استخدام CreateTableElement() method of ITaggedContent interface. علاوة على ذلك، يمكنك استخدام CreateTHead()، CreateTBody() و CreateTFoot() methods of TableElement class لإنشاء رأس الجدول، جسم الجدول، وتذييل الجدول على التوالي. لإنشاء صف جدول، يمكنك استخدام CreateTR() method of TableRowCollectionElement class. يمكنك أيضًا التحقق مما إذا كان مستند PDF الذي تم إنشاؤه يتوافق مع PDF/UA باستخدام Validate() method of Document class.

تعمل مقتطفات الشيفرة التالية أيضًا مع مكتبة Aspose.PDF.Drawing.

توضح مقتطفات الشيفرة التالية كيفية إنشاء جدول في مستند PDF المعلّم:
