Can you store/access data from a table or database via blueprints?

I indexed my chessboard array as such:

57 58 59 60 61 62 63 64
49 50 51 52 53 54 55 56
41 42 43 44 45 46 47 48
33 34 35 36 37 38 39 40
25 26 27 28 29 30 31 32
17 18 19 20 21 22 23 24
09 10 11 12 13 14 15 16
01 02 03 04 05 06 07 08

8

  1. . . 8

so my formulae are quite different, but I already knew them, I just didn’t understand use of UE BP functions.
