I would strongly recommend to use version 2.19 not only because of the 
bass string support (I don’t know whether you need it) but because of a 
better letter positioning. In 2.18.2 the letters are positioned around 
their vertical center instead of the base line so the “d” sits lower 
than the “a” and “c”; see attachment.

Then you can add the following code to the \layout-\context-\TabStaff 
block (f. e. after setting tablatureFormat):

      \override TabNoteHead.before-line-breaking =
        #(lambda (grob)
          (ly:grob-set-property! grob 'Y-offset
            (+  (ly:grob-property grob 'Y-offset) 0.5)))

This moves the letters 0.5 staff spaces up from their original position. 
This code works also in 2.18.2 but it won’t fix the misalignment.

Attached you’ll find the original and the tweaked versions for both 
2.18.2 and 2.19.53.
