I'm not sure I understand you correctly, but perhaps the following
will help:

function! s:bars ()
let newline = ""
let lineno = line(".")
let str = getline(lineno)
let cnt = stridx(str, "|")
let offset = 0
while cnt >= 0
let newline .= repeat(" ", cnt-offset) . cnt
let offset = strlen(cnt)-1
let str = strpart(str, cnt+1)
let cnt = stridx(str, "|")
endwhile
call append(lineno, newline)
endfunction
com! -buffer Bars call s:bars()

Calling ":Bars" with the cursor on a line like:
| | | | abcde | |
produces:
| | | | abcde | |
0 12 3 10 7 1

So it really counts the number of *characters* between bars. If you
really want only spaces to count (so that "7" here would be "2"),
it'll require a little bit more work.

(I'm sure there's a Vim wizard out there who can do all that with only
":substitute".)

Best,
Paul
