On September 3, 2026, Towards Data Science published an article titled “Tables in PDFs for RAG: Don’t Flatten the Grid”, which pointed out that when using tables in PDFs for Retrieval-Augmented Generation (RAG), simple flattening of the grid should not be used. The article emphasized the importance of preserving table structure information to improve model understanding and retrieval performance, and recommended using more refined table parsing strategies to maintain data integrity.
Enterprise Document Intelligence is not a decision tree, but rather a system that includes diagnosis and five combinable operations. In table processing for RAG, the grid should not be flattened. This technology originates from the article “Tables in PDFs for RAG: Don’t Flatten the Grid” published by the Towards Data Science platform, and it is included in the Enterprise Document Intelligence [Vol.1 #B4] series of content.
