title: Rails 3: Drop a table using migration
body: <p>I have a table that I created using the migrations, now I want to get rid of this table.  I'm pretty sure I can just back out that migration, but I can't find the syntax to do that.  I found this question from searching <a href="https://stackoverflow.com/questions/4020131/rails-db-migration-how-to-drop-a-table">Rails DB Migration - How To Drop a Table?</a></p>
  
  <p>but he basically says you can find what you need and provides a link.  I read that link and I didn't see anything that says how to do it.  I saw pieces of it, but I don't know how to put them together.</p>
  
  <p>I see in the migration it has a self.down method, I really just need to know how to call that.</p>
