Bekerja dengan Tabel dalam Tagged PDF di Python

Buat Tabel dalam Tagged PDF

Dengan mengikuti langkah-langkah di atas, Anda dapat membuat tabel yang kaya secara semantik dan dapat diakses dalam dokumen PDF menggunakan Aspose.PDF for Python. File yang dihasilkan memenuhi standar kepatuhan PDF/UA-1, memastikan kompatibilitas dengan pembaca layar dan teknologi bantu. Ini ideal untuk kasus penggunaan yang melibatkan kepatuhan regulasi, audit aksesibilitas, dan penerbitan konten inklusif.

Potongan kode berikut menunjukkan, cara membuat tabel dalam dokumen Tagged PDF:

1. Buat dokumen tagged PDF baru.
2. Atur metadata dokumen.
3. Buat struktur tabel.
4. Buat baris header tabel.
5. Buat baris tubuh tabel dengan sel.
6. Buat baris footer tabel.
7. Set atribut ringkasan tabel.
8. Simpan Tagged PDF.
