To extract tables (including their structure) from PDF documents effectively, especially when dealing with non-English fonts, I recommend using VeryPDF Online Table Extractor. This tool is designed specifically for table extraction from PDFs and offers several advantages:

1. Accurate Table Recognition: It extracts tables directly while maintaining their structure, regardless of the font or language used in the PDF.
2. No OCR Required: Since the document is not a scan, VeryPDF Online Table Extractor works perfectly without relying on OCR.
3. User-Friendly Interface: You can visually select the table area within the document and customize the extraction as needed.
4. Versatile Output Options: Export the extracted table to Excel, CSV, or other formats.

You can try it with your PDF to achieve precise results without relying on coordinate-based extraction or complex transformations. This solution will also work reliably for future PDFs with varying layouts.
