多个子表格识到一起的问题

[stevenwu2017]

hi jsvine,
我遇到一个pdf表格识别不准确的问题,详情如下:
souce code:

if __name__ == '__main__':
   pdf_file_path=r'D:\temp\NBIF-2025.pdf'
   with pdfplumber.open(pdf_file_path) as pdf:
       for idx, page in enumerate(pdf.pages):
           tables = page.find_tables()
           for table in tables:
               sub_page = page.crop(table.bbox)
               im = sub_page.to_image(resolution=200)
               im.debug_tablefinder().show()

识别到的结果:

pdf文件:
NBIF-2025.pdf

请抽时间帮忙看看是什么问题导致,4个表格识别到一块去了,感谢!

I am not sure the maintainer can read Chinese or not. Suggest you can descript your question in English.

I just run a quick test, with below code. No issue found. You can double check your code if any unexpected table_settings applied?

def is_thin_rectangle_exists(obj: dict) -> bool:
    ''' Advised by jsvine - https://github.com/jsvine/pdfplumber/discussions/1242
    '''

    if obj["object_type"] == "rect":
        return obj["height"] < 5 or obj["width"] < 4
    return True

def for_table_quick_test():
    DISCUSSION = r'C:\Users\evmware\Downloads\NBIF-2025.pdf'
    pdf = pdfplumber.open(DISCUSSION)
    page = pdf.pages[0]
    filtered_page = page.filter(is_thin_rectangle_exists)

    im = filtered_page.to_image()

    im.debug_tablefinder()
    im.show()
    im.save('NBIF-2025.png')
