I am experimenting with Visualforce email templates.

1.) Is there a way to run a query for a list of open Leads that belongs to a specific campaign?
2.) Can I then have the results render as a csv?


Essentially I would like something similar to this,

but want it to display information for Lead instead of Account.

Thank you in advance for any help.
