Description William Friedman 2022-10-25 15:34:17 UTC

Description:
In RTL tables, changing the left or right spacing, whether by dragging the edge of the table or by changing the settings in Table Properties | Table | Spacing totally messes up the table, which cannot be fixed by undo. I think this is a regression, since I don't remember this behavior in earlier versions.

Steps to Reproduce:
1. Create a 2x2 table. (Although this happens even in a 1x1 table, it is more obvious in a 2x2 table.)
2. Go to Table Properties | Table and change the text direction to right-to-left.
3. Change the spacing of the left or right edges either by dragging or by changing the numbers in Table Properties | Table | Spacing.
4. Notice that the two rows are now offset. 
5. Undo (ctrl-Z). Notice that the table is still messed up.

Actual Results:
Table edges of the two rows are not aligned. Undo does not restore the table to its original configuration.

Expected Results:
The table spacing should have been uniformly changed for all rows. Undo should restore the table to its original configuration.


Reproducible: Always

This video shows the problematic behavior in action. Note at the end that undoing to the point of reverting to LTR rather than RTL "fixes" the problem.

I confirm it with

Version: 7.4.3.1 (x64) / LibreOffice Community
Build ID: 3793858a34d8fef5b92f8fee233f97766f05e281

Additional information:
For RTL-setting complex text layout has to be active in Tools -> Options -> Language Settings -> Languages

Reconfirmed with 7.4.3.2. This is almost certainly a regression in 7.3, but I am unable to check older versions. Are there others who can be tagged to check this? This bug severely impacts working with RTL tables, to the point that they are completely unusable if any formatting needs to be changed. Thank you.

Comment 4 Fahad Al-Saidi 2023-01-08 05:51:38 UTC

I confirm this bug. I am using 
Version: 7.4.3.2 / LibreOffice Community
Build ID: 40(Build:2)
CPU threads: 4; OS: Linux 5.15; UI render: default; VCL: kf5 (cairo+xcb)
Locale: ar-OM (en_US.UTF-8); UI: en-US
Ubuntu package version: 1:7.4.3~rc2-0ubuntu0.22.04.1~lo1
Calc: threaded

As workaround set table direction to LTR do your format then set it back to RTL.
