Exporting to markdown when table cell contains "|"

I'm using docling to load documents and then export_to_markdown. My data has many tables and I've discovered that some contain the "|" character, breaking the table structure. So I thought, docling should surely escape those when exporting. Or at least offer an option to do so (if not by default).

I see there is [another open issue](https://github.com/DS4SD/docling-core/issues/61) mentioning this.

I considered contributing, but am unsure of where a change like that could fit in. Perhaps adding a boolean escape_breaking parameter [here](https://github.com/DS4SD/docling-core/blob/180e294aada4d97ceeb61556b5f7f310bd078c5f/docling_core/types/legacy_doc/document.py#L441) and then replace any occurences of "|" with regex. Perhaps that is too crude. Any docling-core developer that could point me in the right direction?

Kind regards,
