OCR text and table extraction

Hi eveyone ,
Any blog or link to text and table extraction from images / pdfs , i have tried with pytesseract , camelot ,tabula,easyocr and other available packages all these available packages but it does not work properly , tables are kind of clusttered ( i mean 2 tables separated by little gap between them ) and also some table are borderless (Only have horizontal lines but no vertical lines ) . For this usecase the accuracy is more important than speed .
