Actually I think there's no fully user-friendly solution. Maybe you can try to use the first of the two possible methods currently seen to me.
So the first method is to devise a special config file and include it in the command line for Tesseract. The following values need to be within this config file: tessedit_pageseg_mode 1 or 3 (I recommend 3) textord_tabfind_find_tables T textord_tablefind_recognize_tables T You can play with the last param trying the T or F values. Actually I give no guarantee for the whole method to work, only I found out some clues by studying the code. I suspect corresponding pieces of code may not work perfectly, or there are some more parameters that can influence table recognition. Please try this yourself. It would be nice if you share your results with the community. Sample images are also appreciated. The second method is to pre-process your images. You need to remove lines and borders and pass the cleaned image to Tesseract. There can arise many issues related to this process, but I think there's no need to tell anything else now, except if you express some interest in it.
