calstable
Here is your table type setted using the package cals. As you will find, all rules are visible, and there are no white lines between rules and colours. However, I wold recommend typesetting a classic booktable tabular, without vertical rules, and without any gray shading, see below.
I have defined some shortcuts to reduce coding.
Compared to your original, I have removed side bearing (the left padding in first column and the right padding in the last column, which his customary for academic tables. In addition, I have right aligned the column with figures, but moved the figures to the centre of the column by 1.25em. I also moved the "km" to the column heading. If you prefer one line headings, just increase the column with by some pt.

Classic booktable style tabular
Here I have modified @Levy's code, but made several changes:
- Using tabulary for best fitting column with
- Used booktabs for correctly spaced rules
- Removed side bearing (
@{})
- Gray shading removed
- Columns and headers similar alignment
- Small caps header
