I've been using camelot, which builds on the lower python pdf libraries, to extract tables from pdfs. Haven't tried anything exotic, but it seems to work. The tables I parse tend to be full page or the most dominant element

I like Camelot because it gives me back pandas dataframes. I don't want markdown, I can make that from a dataframe if needed
