AES (and other block cipher symmetric encryption) only use
key and iv (not using iv in ECB mode, but nobody should
use ECB mode). No salt. Or SALT (which is usually considered an
abbreviation for some USA-USSR treaties a long time ago).

So if you want to attempt your tabulation trick, then
you need to deal with key and iv.

And iv changes more than last 5 as demonstrated above.

So your tabulation trick does not work.

PS: It can use salt when generating keys but that is another matter
     and does not influence the problem of a 256 bit random iv.
