Placement of edit and delete buttons for dynamic table

The application I am working on has dynamic tables that gets longer as the user adds more objects. The user is able to edit the properties of these objects and/or delete them.

I'm quite confident of the button placement being on top of the table rather than the bottom (if it was on the bottom, the buttons would move along with the table getting longer which may get quite annoying). However, I'm unsure of the ordering of the button and whether they should be separated (to avoid accidentally deleting).
