Adding column directly from reports issue?

I am sure there is an easy answer to this, but I can't figure it out since the new reports have been released.  None of my table reports will allow me to add a column while I am on the table?  Is there somewhere in the app I need to allow or enable this?  I am an Admin, so I have access to every setting. report etc in our app.

Thanks in advance!
