I suggest adding 1pt to the column spacing for the first 12 columns and 2pt for the totals column to improve readability of 5- and 6-digit numbers when two decimal digits are also displayed. This change works for letter size portrait and landscape, and by my calculations should also work fine for A4.The diff change is
