Nested numbering spanning through longtable

By | June 13, 2018

I would like to find a way how to create such table design using longtable:

My plan fails on point when I actually cant find the right syntax of where to initializace/terminate the \longtable and \enumerate environments, so I am out of my league here completely.

Any help would be much appreciated, I already learned a lot here and hopefully would be able to transfer that information further :) Even pointing in right direction would be great.

Thanks in advance, Tomáš
