Table RAG in Python: Retrieve PDF Tables with Docling and DuckDB

About this lesson

Preserve table structure in PDF RAG pipelines to avoid flattened tables and wrong answers — Docling and DuckDB keep rows intact. Get precise, cell-level answers with verifiable citations by extracting rows, normalizing into pandas, and indexing rows for retrieval. Demo uses Docling, pandas, DuckDB and TF‑IDF (scikit-learn) for fast, interpretable row matching; swap in dense embedders/ANNs as you scale.
