How to know proper DataTables?

Hello, i’m making units using Datatable

it has parts, but i store data separately by Weapon,armor etc

before create or spawn actual unit, i want to know it met requirement to avoid waste

so i can’t just plug it to read datatable, i need to know where it belong

i’m just thinking make another dataTable for only purpose to address their tables

but not assure, what is good practice? thank you!
