Hello,
Today I realized that Org table columns without width cookies get auto-shrunk on hitting TAB:
As far as I remember, the cookie-less columns did not shrink on TAB that way, when this feature got introduced.
Here's a minimal example:
=====
#+title: Width cookies present only on columns that need to be shrunk
#+startup: shrink
|----------+----------------------------------------------------------|
| | <15> |
| Column 1 | Column 2 |
|----------+----------------------------------------------------------|
| 1 | Some content that's longer than the column width cookie. |
|----------+----------------------------------------------------------|
