Table Margins

I am trying to make a ‘skinny’ that will contain nothing but a list of 4 digit numbers…
but if I make the table “wide” enough so I don’t get “8…” there is still a substantail margin on both the left and right side.
How can I remove that? or set it to 4 or 5 points… it looks like it maintains space for the accessory even if you don’t need/want one
