How can I upload a CSV file and expose it in a "views table" for Drupal 7?
As far as I know the short answer here is you can't. Views is pretty much a query building machine.

The next best thing would be to create a script and/or use some views plugin to mass import your nodes from the CSV document and then present them to a view.

And I am proposing a scripted solution in case your nodes are more than 25. Else you might as well do it by hand :)
