Extract table from an image

Question

I have been trying to extract a table with img2table and Tesseract but I always get no extracted tables no matter the different parameters I use. Why? How can I successfully extract the table from this type of image?

from img2table.ocr import TesseractOCR
from img2table.document import Image

# Instantiation of OCR
ocr = TesseractOCR(n_threads=1, lang="eng")

# Instantiation of document, either an image or a PDF
src = "table.png"
doc = Image(src)

# Table extraction
extracted_tables = doc.extract_tables(ocr=ocr,
                                      implicit_rows=True,
                                      borderless_tables=True,
                                      min_confidence=50)

In [2]: extracted_tables
Out[2]: []

The image is:
