unable to get well formated text with tabulator

When I want to write an e-mail with tabulators needed like:
Distance + Km:       1 hour + 66 km    = € 251,00
Time:                       12 hours              = € 581,00

There are many tabulators needed so the “=” sign aligns vertical perfectly. 
But this is impossible. You never get a clear line.
Please tell me how to activate this feature (if it is implemented) or implement this feature. It is very necessary.
