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)
