Re: [O] Tables: Exclude headings in Row Number?

[Neil Jerram]

Does this answer your question?

#+NAME: tt
| num | ID |
|-----+----|
|   1 | A  |
|   2 | B  |
|   3 | C  |
|   4 |    |
|   5 | E  |

#+BEGIN_SRC emacs-lisp :var tt=tt
(length tt)
#+END_SRC

#+RESULTS:
: 5

Best wishes,

Hello all,

I have a table like this:

| ID |

|----|

|  2 |

|  3 |

and I want to know how many rows there are w/o the ID heading

and w/o the horizontal separator.  I found the org-table-toggle-coordinate-overlays

which displays an overlay showing the row number:

However, the heading is included in the row number (which makes sense).

Is there a way to ignore lines above a heading (or mark a heading in some way?

I found a way to add a seq. number by using Calc [1] but I was wondering if

there's a way to tell the org-table-toggle-coordinate-overlays not to count the

heading.

Thanks,
