I already did a table, but not sure how to colour it – aan Oct 29 '19 at 17:08^1use\tnote{1}given that the superscript 1 refers to the corrensponding table note. Apart from that, you might want to clean up your preamble since you currently load packages and tikzlibraries more than once. – leandriis Oct 29 '19 at 19:08\tnote{1}and\tnote{2}I update my MWE now. – aan Oct 29 '19 at 19:16
