So the data that comes from yahoo.finance.options isn't provided by Yahoo? If "no", is there some way to track them down? I'd like to find the data, end-of-day would be fine, so all I'm looking for is a hint to send me in the right direction.
It looks like the data is coming from a finance.yahoo data source. Considering there's no author credit given in the table, if you'd like to make a change to the table's output, you'll need to do it yourself. To do this, please clone the yql-tables project in github, as described on the datatables.org site, make the change, and send us a pull request describing what you did.
