Description callow.mark 2012-11-26 07:56:47 UTC
My document has a table containing another table in one of its cells. The exported XHTML (File->Export->XHTML) is broken such that some of the table borders do not line up vertically and some other borders are missing completely.

Document with problematic table

Export this document to XHTML and compare the original and exported results. The problem is easy to spot.

created separate issue for the missing borders: https://bugs.freedesktop.org/show_bug.cgi?id=57575

Comment 4 Peter Jentsch 2012-11-26 23:15:38 UTC
The nested table formatting seems rather difficult to fix right now, or it would rather require more in depth knowledge of how browsers handle table layout with nested tables. 

You could redesign your table to use spanning instead of nested tables, though. I'm attaching a sample document.

Exported XHTML with LO 7.2 Alpha0: Firefox on left, LO preview on right.

This is a "Works For Me", as shown in the screenshot, testing with LibreOffice 7.2 Alpha0, and opening the exported XHTML in Firefox 88.0.1

This looks like it was fixed for the 7.1 branch, as 7.0.4 still has the misalignment, but 7.1.3 doesn't.

Details for version 7.2:
