I think you want to make a command which, taking into account where you
are on the current line, inserts the correct number of spaces. The
environment variable is $TM_LINE_INDEX, and you should be able to just
insert x - $TM_LINE_INDEX spaces, where x is the next number in your list.
In python this would look something like:
from os import environ as env
from sys import stdout
columnList = [1, 5, 6, 10, 14, 18, 22]
curPos = env['TM_LINE_INDEX']
spacesLeft = [num - curPos for num in columnList if num - curPos > 0]
stdout.write(" " * spacesLeft)
Bind this to the ⇥ key, set the input to selected text or line, and set
the output to insert text, and you should be all set.
