Any clue what the additional advantage having automatic table alignment property.   Why not simply set it to (LEFT/RIGHT); depending on RTL- LTR) with relative checked?

I think DOCX/DOC can't handle that property anyhow; see also Justin L at bug 143983

And well the automatic part is kind of mysterious: I still don't grasp the difference with LEFT/RIGHT & Relative checked. When the UI is capable telling directly what it is doing, why mask it behind "Automatic"

[Perverse Incentive warning: Me wanting a quick fix & avoid solving what's being wrong with the "Automatic" logic]

Cannot confirm with Version: 7.2.1.2 / LibreOffice Community. The properties are still Automatic, with Relative being disabled. Happens only when you shrink the whole table meaning to drag the left/right-most column.

Help says:

|Automatic
|Extends the table horizontally to the left and to the right page margins. This is 
|the recommended setting for tables in HTML documents.

Which means you cannot have it Automatic after changing the table width. Check Automatic to double-check that it reverts to the full size.

Seeing something different here :-)

Expected, not part of the topic. Should be explicit about being about dragging the inner border

Other influence might be zoom-level and screen DPI (72) or OS

No repro here

However, issue still present when doing it from scratch.
1. Open Writer
2. Insert a 3x3 table
3. Merge the middle column
4. Table --> Properties --> Table tab -> Notice alignment automatic
5. Drag the border (left or right from merged cell inside)
6. Table --> Properties --> Table tab --> alignment changed

I probably should open a new report for this; but some conformation in advance would be nice

It seems strange, but I don't repro on Win or Linux.

Version: 7.5.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: 6834fda784f3066a89838cd6cda4fe945f4c7904

Hello! I was able to reproduce the behavior from Comment 7 only on Windows (10):

Version: 7.6.2.1 (X86_64) / LibreOffice Community
Build ID: 56f7684011345957bbf33a7ee678afaf4d2ba333
CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: Skia/Vulkan; VCL: win
Locale: en-US (en_US); UI: en-US
Calc: CL threaded

Steps that I Followed:
1. Open a new Libre office writer document
2. Make sure that the paper format is Letter (Right click->Page Style -> in the Page tab you can see the paper format)
3. Insert a table with more than 2 colums (the table’s position will be Automatic by default)
4. Drag(left/right) a cell border that is inside the table
5. Check the table’s alignment (Go to the table toolbar -> Table properties-> In the table tab, check the alignment option)

Actual result:

The alignment of the table is changed to Left. Please take a look at the video attached.

Expected result:

Considering that the width of the table has not been changed, I would expect its alignment to stick to default, automatic (as in the case of the linux build).

Additional info:

- The bug is reproducible if the style of the page is: A4, B5(ISO), B4(ISO) Legal,  Letter, Long Bond, Tabloid
- The bug is not reproducible if the style of the page is: A6, A5, A3, B6(ISO), B6 (JIS), B5 (JIS), B4 (JIS), 16 Kai, 32 Kai, Big 32 Kai
- The behavior is not reproducible on Linux (Ubuntu 22.04 LST)
- The bug is not reproducible for a nested table
- The bug is not reproducible if changing the width of the inner column (step 4) is done by right-clicking -> click on Size-> Column Width option -> Change the column width -> Click on OK
- Other versions where the bug is reproducible:
7.3.0.0 alpha1 (Windows10)
7.5.0.0 alpha1 (Windows10)
7.0.0.1 (Windows10)
7.1.5.2 (Windows10)


Note: I was not able to reproduce the bug from the first comment with the following versions:
7.3.0.0 alpha1 (Windows10)
7.6.2.1 (Ubuntu 22.04 & Windows 10)
7.1.5.2 (Windows10)
7.0.0.1 (Windows10)
I looked for version 7.3.0.0.alpha0+ but could not find it.
