I had a look and unfortunately the implementation of mode flags is not
easily extensible, thus this cannot easily implemented in independent code.

Also, it would probably make sense to have this being a Calc mode
activated with an org-table formula mode flag, rather than something
implemented in org-table. I don't know how easy it would be to extend Calc.

Turns our this is actually easy. There are two ways to specify
visualization format for table cells: a format specifier like


which results in the units being stripped, and a Calc formatting mode
flag, like


which does not strip the units.
