Automatically choose flavor based on type of table in PDF

[vinayak-mehta]

Continuing the conversation from #102.

@imri:

When you say that lattice should work perfectly - I sort of wish to create a generic way to detect and extract tables without having to know which detection method (lattice / stream) is best for a given document - I want to decouple them as much as possible.

@vinayak-mehta

I get your use-case and it is not possible currently through the library itself. But I see two possibilities which can be implemented (both heuristics):

1. As far as I can tell from NurminenDetectionAlgorithm.java, Tabula first filters out all Lattice-type tables from the document and then looks for Stream-type tables, till it cannot find any more tables. Similarly, we can "couple" both flavors into a single one inside Camelot.
2. We can create a flavor called guess which automatically chooses between Lattice and Stream.

Hi @vinayak-mehta ,

Could you please let me know how i can auto detect when to use lattice and stream. I dont want to check manually rather need an automated way to identify

Thanks in advance
