[Tak Kunihiro]

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.

bug#45915: 28.0.90; deletechar distorts org-table

[Tak Kunihiro]

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?

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.

I still see the problem with GNU Emacs 29.0.50 (build 8,
x86_64-apple-darwin21.5.0, NS appkit-2113.50 Version 12.4 (Build 21F79))
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.

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.

Can someone take a look (org-table-align)?
