Extraction skipping every alternate line and also not extracting headers

[chelsud123]

Description of the bug

In the attached PDF, I am trying to extract the last table. PyMuPDF is extracting it, but skipping every alternate line and is also not extracting the column headers. The following items are attached:

1. Problem_document.pdf : The PDF from which the table has been extracted
2. Table_error.png : The erroneous extraction
   Problem_document.pdf
   

How to reproduce the bug

import pymupdf
from IPython.display import display, Image

doc = pymupdf.open('Problem_document.pdf')
page = doc[idx]
tabs = page.find_tables(add_lines=None)
print(f"{len(tabs.tables)} found on page {idx}")
if tabs.tables:
   for idt in range(0, len(tabs.tables)):
       df_test = pd.DataFrame(tabs[idt].extract())
       display(df_test)

PyMuPDF version

Sorry for the delay.
We have checked out various settings and came to the result that the tables situation on this page as a whole and also the making of each single table cannot be (correctly) detected by the table finder.
You will have to develop own code which for instance adds information via the add_lines parameter to help the table finder.
