recently I am using table to do some statistics, and I want the first column of the table to indicate the row number, as this.

   |  | title|
   |--| -----|
   | 1| A    |
   | 2| B    |

and I want the number of first column grow automatically after creating a new row.

Are there good suggestions about it?

    Place #+tblfm: $1=@#-1 under the table. Now when you move your mouse to the formula and C-c C-c on it, it will recalculate the contents of the first column s.a. to create a sequence of increasing integers.

    I was looking for exactly the same thing (@#). Sometimes searching is faster than asking... ;-D

  • It's possible, but time-consuming, to figure this out from the manual by piecing together info from two sections (sometimes asking is faster than searching, reading, and thinking :) Go to the info-mode manual in emacs (C-h I), Section 3.5.1 of the manual, in an unnumbered sub-section called "Field coordinates in formulas," explains @#-1. Then section 3.5.6, "Column Fomulas," explains the $1=.

    Note that with @wvxvw's answer you can have 0-based indexing with $1=@#-2.

Press S-ENTER in the first column after having put in '1' or another number and it will auto-increment in a new row. Not quite as clever as a formula, but is easier (for me) to remember.

    wvxvw's Aug 12 '15 answer is more generally powerful because it re-numbers all the rows if I insert a row someplace in the table, or if I cut and paste a group of rows.
