Have you read the two pages linked to in the answer from february 5th? Have you executed those procedures, or anything similar, to extract the individual table call images, to feed those to tesseract? So far you have not shown images or any results that show you have used a tabular recognition and cell extraction process at all (which is a preprocess required by the type of input image you have provided so far if you want to significantly improve OCR output quality), so, *hey*, what are your results so far following the sage advice (Feb 5)? (quoted below for convenience:)
