People know a lot about this and they know such a table can't exist, or at least exist accurately. For long efforts, the anaerobic contribution to average power will be negligible, but as the duration gets shorter, that contribution gets more significant. Since anaerobic capacity doesn't depend on FTP and varies from one person to another, there is no way to separate out the aerobic and anaerobic contributions from a single test. Look up Monod critical power to see how the aerobic and anaerobic capabilities can be estimated from two tests; one short and one long.
