Impact: From pixel tables to DataFrames. camelot uses lattice and stream methods to extract tables with row/column spans. Post-process with Pandas: fill missing values, merge multi-index headers. The modern strategy: extract multiple table candidates, then use a confidence heuristic (intersection over union with text layer) to pick the correct one.

For Retrieval-Augmented Generation (RAG), don't chunk by page. Use unstructured or layout-parser: Impact: From pixel tables to DataFrames

from unstructured.partition.pdf import partition_pdf
elements = partition_pdf(
    filename="contract.pdf",
    strategy="hi_res",
    extract_images_in_pdf=True,
    infer_table_structure=True,
    chunking_strategy="by_title"
)
for chunk in elements:
    print(chunk.metadata.category)  # 'Title', 'NarrativeText', 'ListItem'
