Numerical Units in Header Row Only

🚧 THIS IS A TICKET MIGRATED FROM UPVOTY. The original ticket and comments will be available for a limited time over at:

———————————————————————————
It would be nice to have the numerical units such as %, miles, &, etc. in the header row only. All other cell to specify only the numerical values.
For example, Distance (mi) 193, 145, 87

Thank you
