How to Fix PDF Table Duplication in RAG / LLM Pipelines (Python)

Building RAG (Retrieval-Augmented Generation) pipelines is a great way to supercharge LLMs with custom data. However, if your pipeline relies on parsing standard PDFs, you've probably hit a massive roadblock: table text duplication. Most open-source PDF parsers extract table data twice. First, they extract it as a messy, misaligned block of standard prose text. Then, they extract the raw strings from the table cells. This behavior completely destroys the LLM's understanding of the document la...
