If you want to access them as artifacts via code (OR via UI) you'll have to register via code and call them back that way.

Use the following:
https://clear.ml/docs/latest/docs/references/sdk/task#register_artifact

https://clear.ml/docs/latest/docs/references/sdk/task#get_registered_artifacts

Also please note the difference between reporting those tables as data via the logger and as artifacts since the logger saves things as events (plots, scalars, debug samples).
