Is there any way to get automatic row numbers in table?

For example, if I define table contents as

\begin{tabular} % black magic column definition
   \rownumber & foo\\
   \rownumber & bar\\
   \rownumber & baz\\

and get something like

1 | foo
2 | bar
3 | baz

\begin{tabular}{@{\makebox[3em][r]{\rownumber\space}} | r}
  Something \\
  Other stuff \\

Is it possible to start numbering at the second line? i.e. have a header row? TIA. –  Fabian Tamp Oct 10 '12 at 12:00
@Herbert Is it possible what Fabian asked? Starting at the second or third line? –  Isai Jun 29 '13 at 5:22
edit the command \rownumber that it test the value: \ifnum\themagicrownumber>2\relax\arabic{magicrownumbers}\fi` then it puts only the number at the third row –  Herbert Jun 30 '13 at 7:08
@Herbert Do you mean replace \begin{tabular}{@{\makebox[3em][r]{\rownumber\space}} | r} with \begin{tabular}{@{\makebox[3em][r]{\ifnum\themagicrownumber>2\relax\arabic{magic‌​rownumbers}\fi\space}} | r} ? When I do that, I get "Undefined control sequence" errors. –  David Doria Jul 7 '14 at 14:21
@FabianTamp: for the first (column in the first) line use \multicolumn{1}{r}{stuff} and it should not be numbered. –  Herbert Jul 7 '14 at 14:40

You could just make it use a counter...

  \rownumber & Something \\
  \rownumber & Other stuff \\
  \rownumber & MAGIC!

Is there any frendly way to reset the counter between tables? –  miah Jun 21 '11 at 11:56
@miah: Load etoolbox and say \preto\tabular{\setcounter{magicrownumbers}{0}} –  egreg Jun 21 '11 at 11:58
@egreg I put that before my second table but the counter did not reset. I had to use simply \setcounter{magicrownumbers}{0} instead –  David Doria Jul 7 '14 at 14:27
@DavidDoria That code should go in the preamble. –  egreg Jul 7 '14 at 14:29
@egreg Hm, even with that in the preamble, the row numbers do not reset for me unless I clear the counter manually as I explained. –  David Doria Jul 7 '14 at 15:05

A quick plain-format version as well for completenes:

\def\myhalign#1{\halign{\global\advance\rowcount by 1 \the\rowcount\quad##&#1}\rowcount=0}
% Yes, yes, next up in *sniping*: "One problem: you can't use repeating preamble"...

Two problems. 1. Every subsequent \halign will advance the counter even if it doesn't need it. 2. If a row shouldn't be numbered (a header), omitting \the\rowcount would not avoid stepping the counter. The stepping should go in the table preamble. –  egreg Jun 21 '11 at 14:48
@egreg I wasn't aiming for a be-all-end-all solution; just an answer to the question. –  morbusg Jun 21 '11 at 14:51
@egreg: You don't need the @<username>-notation when you're addressing your comment to the answerer/questioner. –  morbusg Jun 21 '11 at 14:57
