With actual tablature, all of the rhythmic elements like note duration, rests, etc. are there. Basically the only difference between standard notation and tablature is how the pitch of the notes is indicated.
Every sheet of tablature that I have ever received as part of any commercially-released instructional material is this way, as is lots of tablature that is available for free on the 'net
That stuff that people call "tab", which is just a bunch of numbers, I don't know what that is, but it sure isn't the tablature that I am familiar with.
