If you are creating a simple form, setting a fixed height for the
table row (in Table | Table Properties, Row tab) usually does the job.
People tend to stop typing when they find that the text disappears...
For more control, use a protected form with a text form field set to
allow a maximum number of characters (as Jezebel suggested). You still
need to put the form field inside a fixed-height table cell, since the
form field doesn't prevent users from pressing Enter.
A macro can provide even more control. See:

form in Word

What is the best way to create them?

This article also has links to a series of articles (by Dian Chapman)
which describes the use of protected forms in detail.

I am trying to lock down a table to only allow a specific number of
alpha-numeric characters to be inserted into the table. It is a one
by one table.
