On the subject of scraping data from OCR'd tables: I heard from a colleague who moved into finance, that there's a mini arms race going on between some funds(?) who are subject to regulatory requirements to release financial performance metrics but for a variety of reasons would rather not (and certainly would rather not make the data machine readable), and other hedge funds who want to run automated trading strategies off said released figures. They keep obfuscating the tables to make them harder and harder to parse algorithmically while still remaining theoretically human-readable. Great fun no doubt for everyone involved.
