While checking bug 80668, I see that with LibO 4.2 and above, the table borders and background colors are not retained for attachment 102656 [details].
How it looks in 4.1 vs 4.2 and above - attachment 102682 [details]
LibreOffice 18.104.22.168 rc
Not bibisectable unfortunately.
1. Download attachment
2. Open Writer
3. File -> open (select your downloaded html file)
Obeserved: The borders can be seen on screen but they are empty (no color) and the borders are not black (just the outline is visible)
Expected: The color from the original html file is retained and the borders are black as seen in the image attached in the description
Minor - can slow down professional quality work (you'd have to reapply the colors after opening the file).
Medium - regression so bumped up from low
Digging into the html code, the table border property is set to 0, but each cell has a css class equal to 'bordered', which is:
border: 1px solid #000;
With the table headers that are missing a background color, the rows have the css class equal to 'bg-gray', which is:
I believe that LibO is ignoring most CSS styles defined in <style> tags and putting in standard text document styles instead of default html styles, as further illustrated with bug 81297.
the table borders are due to the same root cause in CSS import as
bug 81276 but not the cell backgrounds...
actually this is a duplicate of the other bug - the fix for it
fixes the table background too when backported to 4.2 and 4.3;
so on master there is a different regression that
affects the table background.... i vaguely remember seeing
a bug about table backgrounds on master but can't remember now...
*** This bug has been marked as a duplicate of bug 81276 ***
taking this for the cell backgrounds as seen in 4.4 series
