Why don't pdf's generated from a Microsoft Visio diagram with excel populated tables parse?

### Question

So here's the thing. I've tried multiple ways to convert PDFs that have been exported from visio with tables in them. The text will be extracted but the table information isn't maintained. I've also referred to the other question in regards to PDF conversion and still had the same issues. Is there something I'm missing here? I'm trying with OCR I'm trying with all of the different types of conversion parameters to make sure tables are prioritized and I'm still not getting any tables even though they're pretty well rendered in the PDF. Is there an optimal configuration parameter set for parsing these sorts of tables?
