org-mode table editor behaves strangely

Question

1. With cursor in row 2, col 3

| a | b | c  |
| 1 | 2 | 3 _|

2. Pressing <TAB> creates a new row:

| a | b | c |
| 1 | 2 | 3 |
|   |   |   |

3. Type more than one character and press tab. Vertical bars have been removed from rows 1 and 2:

This isn't the expected behaviour, is it?

Oddly, when I copy and paste from the file into this editor, the bars appear as expected. Spacemacs version: [email protected] (spacemacs)

Org mode version 9.1.5 (9.1.5-1-gb3ddb0-elpaplus @ /home/sweidman/.emacs.d/elpa/org-plus-contrib-20171225/)

I tried switching fonts from Source Code Pro to Ubuntu Mono but the problem persisted.

When I start emacs with "emacs -Q", the problem disappears using org-mode: Org-mode version 8.2.10 (release_8.2.10 @ /usr/local/share/emacs/25.1/lisp/org/)

If I close and re-open the file, the table appears correctly formatted.

Answer 1

I answered my question here and using it to close this question.

Steps to fix this issue:

1. I downloaded the latest org-plus-contrib-yyyymmdd from elpa. The file is available only in .tar extension. (Convert that to ZIP online if you do not have archive program that can handle tar extension)
2. I extracted the ZIP archive into C:\Users\path_to\AppData\Roaming\.emacs.d directory and restarted emacs.
3. After restart, ran M-x org-version and the version had changed to 9.1.6 from 9.1.5

This fixed the table formatting issue. (I'm not a 100% sure of the cause of the problem, but this update fixed things, the way they should be)
