Support for Vertical Forms in Docling

[jnm-ronquillo]

Requested Feature

I'd like Docling to parse properly a vertical form in a pdf file. For example in the following code:

from docling.document_converter import DocumentConverter

source = "https://drive.usercontent.google.com/download?id=1kdT8UWLNnJ5XGiXoyyNCImWzoLucBNbq&export=download&authuser=0&confirm=t&uuid=b7768e5f-3e28-49d4-bd80-2f5856c398a1&at=APvzH3qJRJ11Y_63usKNHntbOMKO:1736036888144"
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown())

The output is as follows:

Name

Last Name

Age

Mario

Bros

30

Occupation Plumber

Address

Marital Status Single

Minecraft 123

Which is difficult for a LLM to answer questions about structured data.
Another example:

from pathlib import Path

from docling.backend.docling_parse_backend import DoclingParseDocumentBackend
from docling.datamodel.base_models import InputFormat
from docling.datamodel.pipeline_options import (
    EasyOcrOptions,
    OcrMacOptions,
    PdfPipelineOptions,
    RapidOcrOptions,
    TesseractCliOcrOptions,
    TesseractOcrOptions,
)
from docling.document_converter import DocumentConverter, PdfFormatOption

def main():
    input_doc = Path("./NameLastnameAge.pdf")

    pipeline_options = PdfPipelineOptions()
    pipeline_options.do_ocr = True
    pipeline_options.do_table_structure = True
    pipeline_options.table_structure_options.do_cell_matching = True

    # Any of the OCR options can be used:EasyOcrOptions, TesseractOcrOptions, TesseractCliOcrOptions, OcrMacOptions(Mac only), RapidOcrOptions
    # ocr_options = EasyOcrOptions(force_full_page_ocr=True)
    # ocr_options = TesseractOcrOptions(force_full_page_ocr=True)
    ocr_options = OcrMacOptions(force_full_page_ocr=True)
    # ocr_options = RapidOcrOptions(force_full_page_ocr=True)
    # ocr_options = TesseractCliOcrOptions(force_full_page_ocr=True)
    pipeline_options.ocr_options = ocr_options

    converter = DocumentConverter(
        format_options={
            InputFormat.PDF: PdfFormatOption(
                pipeline_options=pipeline_options,
            )
        }
    )

    doc = converter.convert(input_doc).document
    md = doc.export_to_markdown()
    print(md)

if __name__ == "__main__":
    main()

The output:

| Name       | Last Name     | Age            |
|------------|---------------|----------------|
| Mario      | Bros          | 30             |
| Occupation | Address       | Marital Status |
| Plumber    | Minecraft 123 | Single         |

Which is not exactly the output desired because the pdf content is not a table. I attached the pdf example used.
NameLastnameAge.pdf
