Hello screen reader mavens and web accessibility afficionados,

I am trying to get a sense of the relative accessibility of data tables (not layout tables) in different web-based formats. 

When reading a tagged PDF file using the most recent versions of Jaws and Window-Eyes, are complex data tables as accessible as those written in HTML? Is it possible to craft a PDF data table that provides as much contextual information as an HTML table, e.g., headers for columns, headers for rows (when required), and so on?

Overall, I know that HTML is much more accessible than PDF, both in terms of accessibility and number of people who can access it. But I need to understand the potential for accessible tagged PDF.
