LaTeX has a tabbing environment but it is not directly supported by LyX,
so you will have to use some ERT. Have a look at the .lyx file appended
at the end (you will have to copy and paste it as I cannot attach files).
The first line after \begin{tabbing} sets the tab stops.
Each line is ended by \\ and you go to the next tab stop by \>.
I used hard spaces (control+space) for visual alignment in LyX but they
are simply ignored in the output (one space is the same as one thousand).
Have a look at a LaTeX book for other commands other than \>.
