I'm an accessibility expert. When auditing a website, I'm usually (among many other things) try to find some tables that don't meet the requirements (e.g. missing th elements in data tables).
As it is cumbersome to search for such tables manually, it would be very handy to be able to search for them using google, the same way that (for example) filetype search work:
filetype:pdf site:access-for-all.ch
I tried a little bit around, and couldn't find a solution. Although Google has a tables search…

…I couldn't make it work for me. I tried searching for "zugang für alle" Audit and site:access-for-all.ch preise, but none of them showed results, although there clearly is a table with "preise" in it on http://www.access-for-all.ch/ch/zertifizierung/kostenuebersicht.html.
Any idea on how this works? And how to make it suit my needs (searching for tables in general)?

Have you tried using an existing accessibility checker?
I would expect at least some of the tools on this list would check table headers for you.
