Bill Slawski says, “There are many pages on the Web that are filled with data in the form of tables. It’s possible that if you weren’t paying attention you may have missed Google Table Search entirely—it hasn’t gotten a lot of press as far as I can tell. If you include tabular data on the pages of your site, though, you may be able to find tables from your site included in the results from a query in Google Table Search.

Imagine that I am looking to buy a new camera lens, except I’m not sure which one to purchase. I’ve heard good things about Nikon lenses, so I go to Table Search and look for [ single lens dslr nikon].  The first table returned gives me some choices to compare different lenses”.
