How can I prevent the row height from changing when copy&pasting a calc table to a website?

[ChunkyRook]

I’d like to copy&paste parts of a Calc table into the CMS of my website. This works perfectly on my desktop computer (the resulting html code features a row height of 17px), but when I use my laptop, it results in double the row height (34px), despite the fact that the tables, all the settings and the browser / LibreOffice versions are identical.

Any idea what may cause this and how to prevent this? Thanks for your feedback!

I’ve managed to locate the root of the problem. Not Calc is to blame, but Windows: In the display settings, my Windows Surface uses an option “Change the size of text, apps and other items” to 200%. If you reduce this option to 100%, after the re-boot everything copy&pastes with the original row height.
