* Table > Insert Table: Okay (using the Default Style) - this creates a table with black cell borders in Writer
* Export as HTML, open in Browser (checked with FF, Chromium) - no table
Running this with 5.2.7 works and the exported file looks like this:
<td width="25%" style="border-top: 1px solid #000000; border-bottom: 1px solid #000000; ...
with master (and supposedly 6.1) we get
<td width="50%" style="background: transparent" style="border-top: 1px solid #000000; ...
Removing the duplicate style entry manually solves the issue
<td width="25%" style="border-top: 1px solid #000000; ...
Thank you for reporting the bug.
