It depends on exactly how the table is defined.
What is the INDEX clause from the MIB file?

Each string will be turning into a sequence of individual ASCII characters.
So the index for row 1 will probably be
       4.'m'.'i'.'k'.'e'.5.'h'.'e'.'l'.'l'.'o'
and for row 2
       4.'a'.'m'.'f'.'i'.5.'c'.'h'.'r'.'i'.'s'

Note that each string is preceded by its length.

If the INDEX clause looks like   { index1,   IMPLIED index2 }
then you should omit the second length value
(i.e. 4.'m'.'i'.'k'.'e'.'h'.'e'.'l'.'l'.'o')
   But this *only* holds for the final index value.
All others will include the length subidentifier.

(That's not strictly true in the case of fixed-length strings,
 but my guess is that this isn't relevant here)

OK?
