I am using emacs 27.1 with orgtbl-mode.  On certain condition, typing
<deletechar> distorts alighment of a table.  Then, typing <up> moves
previous line but far right position.

|   | rownames |     |   | rownames |
| / | <l>      |     | / | <l>      |
|---+----------| ->  |---+----------|
| / | a        |     |  | a        |

Here is a recipe to reproduce the glitch started from emcas -Q.  I
hope that together with bug#45091, this would be fixed before 27.2.

1. Create a buffer with (text-mode) and yank following table.

|   | rownames |
| / | <l>      |
|---+----------|
|   | a        |

2. (progn (require 'org) (call-interactively 'orgtbl-mode))
3. Move point to the first column and the third line with letter 'a'.
4. Hit <S-return>.
5. Hit <deletechar>.
6. Hit <up>.

I confirm that there still is following problem on 27.1.91.
Could someone take a look and show me work around?

I cannot reproduce this with latest Org stable version 9.4.5.

Can you try again and report?

See https://orgmode.org/org.html#Installation on how to install
using Org’s git repository if you want to try the latest version.

I downloaded Org 9.4.5 and reproduced the problem on 26.3, 27.2,
and 28.0.50. Here is a recipe again.

I confirm that there is still problem with org-table
on Emacs 29.0.50 with org-version 9.5.
I created a function to produce the problem as shown below.
Can you try again?

I confirm that there still is the problem with org-table on Emacs
28.0.90 pretest with org-version 9.5.1.

Here is a recipe to reproduce the problem.  I still have to stick to
26.3.

 1. emacs -Q
 2. (defun emacs-bug-reproduce-45915 () ...)
 3. (call-interactively 'emacs-bug-reproduce-45915)

Dear Ihor

Thank you for the patch.  I applied the patch to org-table.el on Emacs
28.0.90.

And I still see the problem there.  Is the problem solved by the patch
on your environment?

Tak

The problem was solved on my side, but _not_ using your reproducer
explicitly. If I save the buffer from your reproducer as a file and
later open in, the patch does solve the problem. However, when I run the
reproducer as is, a similar-looking problem emerges.

Using your reproducer, something very strange is going on.
With the patch, <delete> is correctly mapped to org-delete-char, which
calls (delete-char 1) at some point. However, this (delete-char 1)
somehow deletes 2!! chars instead of 1. This should be some tricky Emacs
issue (bug?). In any case, I am not ready to dig into what is going on
in Emacs. I do not think that such problem is going to appear during
normal Emacs usage. At least, I was unable to reproduce it by other
means than your reproducer function.

To illustrate the issue, one can use the following version of the
reproducer. Feel free to report this to Emacs upstream.

(defun emacs-bug-reproduce-45915 ()
  "Reproduce bug#45915."
  ;; (gnus-read-ephemeral-emacs-bug-group 45915)
  (interactive)
  (with-current-buffer (get-buffer-create "*temp buffer*")
    (erase-buffer)
    (require 'org)
    (orgtbl-mode 1)
    (insert (format "emacs-version: %s, org-version: %s\n" emacs-version org-version))
    (insert "|   | rownames |
| / | <l>      |
|---+----------|
|   | a        |"))
  (switch-to-buffer-other-window "*temp buffer*")
  (execute-kbd-macro (kbd "M-< C-n C-n C-n C-n C-f C-f"))
  (message "I will hit S-<return>.")
  (sit-for 2)
  (execute-kbd-macro (kbd "S-<return>"))
  (message "I will hit <delete>.")
  (sit-for 2)
  ;;  (execute-kbd-macro (kbd "<delete>"))
  (delete-char 1)
  (message "I will call previous-line.")
  (sit-for 2)
  (call-interactively 'previous-line))

Best,
Ihor

issue (bug?). In any case, I am not ready to dig into what is going on
in Emacs. I do not think that such problem is going to appear during
normal Emacs usage. At least, I was unable to reproduce it by other
means than your reproducer function.

To illustrate the issue, one can use the following version of the
reproducer. Feel free to report this to Emacs upstream.

(defun emacs-bug-reproduce-45915 ()
  "Reproduce bug#45915."
  ;; (gnus-read-ephemeral-emacs-bug-group 45915)

    (require 'org)
    (orgtbl-mode 1)
    (insert (format "emacs-version: %s, org-version: %s\n" emacs-version org-version))
    (insert "|   | rownames |

I still see the problem with GNU Emacs 29.0.50 (build 8,

of 2022-05-23 with org-version 9.5.3.

I create org-tables and revise these everyday.  On duplication of a
cell, I hit S-<return> often. The problem occurs, with my use case, once
in 5 minutes. IOW point moves unexpectedly once in 5 minutes.

I think that there is an issue in `org-table-copy-down'. However, I
cannot tell what specifically is not good.

Is this issue of Emacs instead of Org?

To clarify, I haven't applied the patch onto Org upstream.
Before the patch, the table is distorted because of an omission in Org.
After the patch, the table is distorted only using your reproducer
specifically, and the issue appears to be on Emacs side.

Ihor

I now applied the patch onto main via 65e19a081.

This should solve part of the problem.
The remaining part should be solved on Emacs side (AFAIU).

I confirmed that delete-char still deletes two letters on

I found out (org-table-align) in (org-table-copy-down) makes
this situation.

I think that the thread has been lost because the bug has been assigned
to Org. I now tried to reassign the bug back to emacs.

I see a light.
With the following patch, <delete> deletes only a letter.

The (org-table-align) inserts string with text properties.
It seems that the text properties matter.

However, I do not understand what's going on there. Can you take a look
(org-table-align) with this hint and revise it in correct way?

Why do you think your proposed change is incorrect?

Rather than asking us to study how org-table works and why it
misbehaves in this case, would it be possible for some Org expert to
explain that in simple terms, so that the relation of what happens to
the relevant core Emacs features could be easier to realize?  For
example, what are the text properties involved in this case, the ones
that substring-no-properties removes?  Is it possible that one of
these properties is 'composition'?

Dear Eli, thank you for the response. I really want to fix it to
switch to 28.2 from 26.3!

1. Following function will create a problematic org-table.

(defun emacs-bug-reproduce-45915 ()
  "Reproduce bug#45915."
  (interactive)
  (with-current-buffer (get-buffer-create "*temp buffer*")
    (erase-buffer)
    (require 'org)
    (orgtbl-mode 1)
    (setq org-table-copy-increment nil)
    (insert (format "emacs-version: %s, org-version: %s\n" emacs-version org-version))
    (insert "| 1 |"))
  (switch-to-buffer-other-window "*temp buffer*")
  (execute-kbd-macro (kbd "M-< C-n C-f C-f"))
  (message "I will call #'org-table-copy-down.")
  (call-interactively #'org-table-copy-down))
;;; (call-interactively 'emacs-bug-reproduce-45915)

2. Buffer is with the 1x2 table as shown below. <delete> deletes one
letter on the first row, and it does two letters on the
second row.

  emacs-version: 28.2, org-version: 9.5.5
  | 1 |
  | 1 |

3. I wonder what is the difference between two lines.
I examined each line with following statement.

  (buffer-substring (line-beginning-position) (line-end-position))

line 1 returns: "| 1 |"
line 2 returns: #("| 1 |" 1 2 (display (space :relative-width 1)) 3 4
(display (space :relative-width 1)))

4. Although I do not know how to understand the return for line 2,
I speculated the problem is something to do with text properties.

5. It is (org-table-align) that generates and inserts the second line
with text properties.

6. I tried to remove text-properties from string to be inserted by
(org-table-align) using substring-no-properties (as shown in the
patch). Now, both lines returns the same "| 1 |". Problem disappeared.

7. Since I do not know intention why (org-table-align) wants to give
text properties to tables, I cannot tell the side effect of the patch.

TIA

No, it doesn't delete 2 characters in the 2nd line, it deletes just
one.  After you press <Delete>, type C-b (to go to the space between
the two '|' characters, and type "C-x =".  You will see this:

  Char: SPC (32, #o40, #x20, part of display "  ") point=51 of 54 (93%) column=1

Note the "51 to 54" part: there's a 'display' property there that
covers _two_ buffer positions, not one.  That's because the two
'display' properties on the two SPC characters before the deletion
have the same value:

>   (buffer-substring (line-beginning-position) (line-end-position))
> 
> line 1 returns: "| 1 |"
> line 2 returns: #("| 1 |" 1 2 (display (space :relative-width 1)) 3 4
> (display (space :relative-width 1)))

Those two 'display' properties are now displayed as a single stretch
glyph, because two adjacent text properties with the same value are
indistinguishable from a single one that spans all of the buffer
positions.

This is not a bug, this is how Emacs always worked.

The question is now why is this a problem for you, and how it affects
Org Table.  The solution, if there's a need for one, should IMO come
from the Org side.

I see. I understand that 'display' properties on an org-table matters.
I took a look for (org-table-align) and found that
`org-table-separator-space' defines the text properties as shown below.

org-table.el: (defconst org-table-separator-space
org-table.el:   (propertize " " 'display '(space :relative-width 1))
org-table.el:   "Space used around fields when aligning the table.
org-table.el: This space serves as a segment separator for the purposes of the
org-table.el: bidirectional reordering.")

Although I still do not understand the purpose of `:relative-width',
problem disappeared with following configuration.

  (with-eval-after-load "org-table"
    (setq org-table-separator-space " "))

I have an impression that default characters on
org-table-separator-space is problematic.

Yes, and that's exactly right for when the table could include
bidirectional (i.e. mixed L2R and R2L) text.

I don't think this is the right solution.  One possible solution that
is better is to bind <Delete> to an org-table specific command, which
would insert some character displayed as a thin space between the two
spaces that have the 'display' property.  But I'll let Ihor chime in.

What do you mean by "default characters"?

One other possibility is to use a slightly different :relative-width
factor for the two spaces in a table cell: one with the value of 1,
the other with 1.001 (say).  They will be indistinguishable on
display, but since the values are not equal, both stretch gfyphs will
be displayed, not just one.

Function (org-table--align-field) in org-table.el sandwiches 
text by org-table-separator-space as shown below.

    (concat org-table-separator-space
 	    prefix
 	    field
 	    suffix
-	    org-table-separator-space)))
+	    (propertize org-table-separator-space 'display '(space :relative-width 1.001)))))

I confirmed that this modification works good.

Let me take the statement back.

OK. Now I understand <delete> only deletes one letter.  Two spaces are
shown as one letter, as expected.

To have a distorted table soon after deletion of text is OK.

However, when two spaces are shown as one letter, point moves randomly
when I press <up>.  I cannot keep editing with this condition.

I show recipe to reproduce this situation. Is there a trick to move
point in expected way?

  ;; (gnus-read-ephemeral-emacs-bug-group 45915)

    (erase-buffer)
    (require 'org)
    (orgtbl-mode 1)
    (insert (format "emacs-version: %s, org-version: %s\n" emacs-version org-version))
    (insert "| 1 |   |   |   |   |   |   |   |   |"))

This is an unrelated bug, now fixed on the master branch.

(A workaround is to press C-f or <RIGHT> before <UP>.)

This is a good idea. I used it to fix the reported issue.
