Locking Exact Row Height

I am working with a 13-page table that has (in the past) only been printed
out and filled-in by hand. I have been tasked with re-formatting the
document so that the row height for each cell is locked in 'exactly' as it
currently is, such that digitally type-written versions of the form will take
up the same space as the hand-written form. In other words, each page needs
to have its cells locked at their current height so they'll be equivalent to
the version that is hand-written. This is so that hand-written and
type-written versions of the document will have the same questions on the
same page, and will thus be easy to read interchangably--some students will
continue filling them in by hand, while others will begin doing them
digitally.
So, here's the question: Is there a quick way to lock the row height of
each cell, instead of figuring out the height and then setting it as
'exactly' for every single cell? I should note that the cells are of varying
heights, so you can imagine that doing this for a 13-page table would be
awful. Furthermore, I may be given similar tasks with other documents in the
future. So, finding a quicker way to do this would be of great assistance.
Help!
