These 220 (22x10) intersections are known as the '220 gates' (not to be confused with the 231 gates formed by pairing the 22 letters with each other).
By chance the number of pips in the four suits 1-10 also equals 220.
Most esoteric schools allocate the pip cards to the sefirah according to their number (all aces to keter, all 2's to Chokmah, etc.). However, if you follow old tarot gaming rules (two suits rank low to high, 2 high to low), then you can model them neatly in a 22x10 table:

B= Batons
C = Cups
S = Swords
D = Deniers
Reading across you will see :
First row - 10 'b's, 1 c, 10 S's and 1 d = Keter (10 Batons, Ace of Cups, 10 Swords, Ace of Denier/Coins)
Second row - 9 b's, 2 c, 9 S's and 2 d's = Chokmah
etc.
You can also read down to connect each of the pips with a Major card, for example:
First column | 10 b's (10 Batons) under 0 (the fool)
Second column | 9 b's (9 Batons) and 1 C (Ace of Cups) under I (The Juggler)
Third column | 8 b's (8 Batons) and 2 C's (2 Cups) under II (The Popesse)
...
Twenty-second column | 10 d's (10 Deniers/Coins) under XXI (The World)
You can move the suits and majors round to suit your own preferred school of thought as to their ordering (I use the TdM, Alef with 0 The Fool).*
