Description Jan Chroust 2021-03-05 15:22:02 UTC
I have a docx document generated from some web app. In previous version of writer 7.1 crashed when I opened the document (bug 140137 - resolved in version 7.2). Now it is OK to open it, but one of tables in document has a bad view (aganist view in MS Ofice). Maybe is a bug on web app which was generated the document, but why MS Word open it correctly?. 
There is probably problem with merged cells on rows from 6 to 11. In these rows it should be merged columns from 1 to 11 and the last column should be separately. Like in the view in MS Word 2019.
Screenshots of bad view od table in Writer and correct view of table in MS Word 2019 are in attachments.

Steps to Reproduce:
1. Open the document
2. Go to the page 8
3. See the table

Actual Results:
Bad view of the table

Expected Results:
Correct view of table

Reproducible: Always

User Profile Reset: No

Additional Info:
Correct view of table

Original attachment 170247 [details] is 19 pages in MSO. Trouble table is page 8. 
Trimmed down (wasn't explain how but seems correctly) attachment 170265 [details] is 3 pages, same table at page 3. Lo opens 2 pages, no table.

Note: We have few bugs with generated content (always search before submitting) where they are usually not fully in standard, but MSO still reads them.

If document is resaved in MSO, both compatible or new, LO opens it properly. Here I attached compatible one from MSO as attachment 170270 [details].

I bibisected improvement in 41 and got "Drop redundant typedef" by S. Bergmann. So that's of no help.

Original document claims to be from 
<Application>Microsoft Office Word</Application>
and 2007.

Reduced version is from 
<ap:Application>Microsoft Word for the web</ap:Application>
and 2016.
