/*
# proc: lgl_tbl - Given a set of legal-parm-value-strings and coresponding
# proc:        code-number-strings, makes a neat table of the strings and codes.

Input args:
  n_legal: Number of legal-value string-code pairs.
  legal_valname_p: The legal-parm-value strings, as an array of
    pointers.
  legal_valcode_str: The corresponding code-numbers, as strings stored
    in an array whose second dimension is 2.  These numbers must be in
    the range 0 through 9.

Output arg:
  table: The table of string-code pairs, as a string.  Allocated by
    caller; allocate large enough for added spaces, to the left of
    the first col and between first and second col.
