I don't believe there is any sort of actual _standard_ that says HT =
column mod 8. 

On some old mechanical typewriters, you could set mechanical tab stops
where ever you wanted, to make typing tables etc easiser. Early
printers also had configurable tab stops (not mechanical).

Good editors also have configurable tab stops. 

But the only portable way to use tab stops is to insert spaces, not HT.
