説明
Bug
In docling-core, the MarkdownTableSerializer transforms DoclingDocument headings and titles into markdown headings (i.e., text with preceding # symbols). According to the markdown specs, you can’t use headings, blockquotes, lists, horizontal rules, images, or most HTML tags when formatting text within tables and most applications will not render those headings properly.
Steps to reproduce
Convert Docling's test file table_with_heading_02.html to markdown or check its ground truth file table_with_heading_02.html.md
