Why is the order of extracting the contents in the table cells wrong?

[xielulu1994]

Describe the bug

extract_table() to extract table content, and find that the order of extracted text in individual cells is inconsistent with the original text.

Code to reproduce the problem

table_text_items: List[tuple] = []
    with pdfplumber.open(file_path) as pdf:
        for page in pdf.pages:
            table = page.extract_table()
            lines: List[str] = []
            if table:
                for row in table:
                    for line in [item for item in row if item is not None]:
                        if line:
                            lines.extend(line.split("\n"))
            if lines:
                table_text_items.append((page.page_number, lines))

Please attach any PDFs necessary to reproduce the problem.

If you need to redact text in a sensitive PDF, you can run it through JoshData/pdf-redactor.

Hi @xielulu1994, and thanks for your interest in pdfplumber. Without access to the PDF itself, it is difficult to provide tested advice. However, from looking at the screenshots, my guess is that the bounding boxes of the characters in the cd \d[...] text are a bit above the rest of the text. Try this:

page.extract_table({ "text_y_tolerance": 5 })

... although you may have to try adjusting that 5 value higher or lower, depending on the specifics of the PDF.
