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

[Neil Jerram]

Well, the code for this is in `org-table-overlay-coordinate-overlays' in org-table.el.  There isn't an existing flag for your request, but of course you can play with that code as you like.

For example, if the `(setq ih (1+ ih))' is changed to `(setq id 0 ih (1+ ih))', the row numbers will start again from 1 after each hline.

Best wishes,

I also re-read my initial question and your response *does* address my

mis phrased question.  To rephrase my question, I have a table

with these values:

| heading col 0  | heading col 1 |

| ------------------ | ----------------- |

| A                   | B

| C                  | D

I found the org-table-toggle-coordinate-overlays

which displays an overlay showing the row number:

I would like to know if there's a way to influence org-table-toggle-coordinate-overlays

(e.g. some flag like "don't count rows before headings")

Thanks,

Hi Neil,

Unfortunately, no - This code will print the number of rows in my table - it does

not add a column to my table, with numbering starting at the first row under the

headline.

I really like the example, where I can mess with the table using lisp though - thank

you!

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:

https://www.evernote.com/l/AOJvD5ty6RRIBYAcSWV-047CKCHT5NIAhl8

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,
