I'm working on a Python project where I need to extract structured information from scanned PDF documents. I'm using OCR, but the extracted text often has incorrect formatting, especially for tables and multi-column layouts.

I've tried converting the PDF pages to images and processing them with Tesseract, but the results are inconsistent for low-quality scans.

I'm looking for suggestions on:

• Improving OCR accuracy for scanned PDFs.

• Preserving table structure.

• Python libraries or preprocessing techniques that work well for this use case.
