Since October there is a new version, v4: “Added a new OCR engine that uses neural network system based on LSTMs, with major accuracy gains. [..] Added trained data that includes LSTM models to 123 languages.”
No idea how well it does for structured content like tables.
There seems to be a recent v2 of a javascript port (i.e. Tesseract v4 compiled to wasm), if anyone wants to do OCR in their browser:
