I can confirm this with LO, but only with the specific table of the attachment in the bug report.

I couldn't reproduce it
- with a new table in the attached document
- with o acopy of the table in a new document

So I set the status to NEW (but perhaps this kind of confirmation is not strong enough).

Good point. It's reproducible when changing some border line width's from 1 to 1,25p.
Comment 3 Dieter Praas 2017-09-26 21:11:11 UTC
Yes, I could reproduce it with an new table in a new document and a border line width of 1pt
Comment 4 Telesto 2018-01-01 12:16:22 UTC
Seems to happen with a default table too (since table border is set to 0,5pt instead of 0,05pt)

fdo#75260: Correctly draw double lines for both Writer and Calc.
Fix all sorts of incorrect double line handling in drawinglayer in order to
draw thick-thin double line types correctly.  Also change handling of border
lines in writer tables. There are still some outstanding issues but it's
much better than how it was before.

Also realized that Word and Excel handle simple thin double lines differently;
Word varies widths of all of the lines and the gap whereas Excel only has one
fixed size for its double line.  For this reason I decided to add a separate
double line type (DOUBLE_THIN) to handle Excel's double line.

Dear Telesto,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Feel free to come ask questions or to say hello in our QA chat: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
