Sub table of a subtable of a Table

[kevin_nuclear]

I am working on a project that has three component requirements that will be tested. A-level, B-Spec, and C-Spec. A-level links ot B-Spec which link to C-Spec. Each A-level is unique, but can be linked to multiple B-Spec. Eac B-Spec can have links to many C-Spec. The C-Spec can also be tied to multiple B-Specs, that is, one C-Spec can be used "multiple" times for different B-Specs, but only is linked to a certain B-Spec once. The C-Specs are tested, which will then allow us to either pass or test a B-Spec, and then pass or test all the A-Specs.

I am trying to build a set of tables and sub-tables that will allow me to note the results of different tests for each C-Spec, then B-Spec, and finally A-level. Should I use my A-level as the Unique key for the main table, B-Spec as the key for the first sub-table, linking back to the A-level and down to the C-Spec, or should I use unique keys for each of the sub-tables and link up and back to the A-level that way? Below is an example of how the data is currently. I cannot get any of the excel websites to upload properly.
