Duplicated Information When Extracting Tables Inside Table Cells

[ricdurvin]

Bug

When extracting tables from the attached PDF (table_inside_cell.pdf) using pymupdf4llm, I observed that information is duplicated in the output (pymupdf4llm-table_inside_cell.md). Specifically, when there is a table nested within a cell of another table, the content appears multiple times in the extracted result.

Steps to reproduce

1. Run pymupdf4llm on the attached table_inside_cell.pdf.
2. Review the output.
3. Observe that the content from the nested table is duplicated in the output.

import pymupdf4llm

def extract_with_pymupdf4llm(file_name):
    text = pymupdf4llm.to_markdown(file_name)
    return text

if name == "main":
    file = "PDF_PATH"
    text = extract_with_pymupdf4llm(file)
    print(text)

pymupdf4llm-table_inside_cell.md
table_inside_cell.pdf

Nested tables are not supported: not by PyMuPDF's table module and neither by the Markdown syntax standard.
When nested tables are being analyzed, results are therefore not predictable. The table module will do what it can to establish a flat structure of one table in the identified boundary boxes area.
