Export HTML table to pdf produces strange formarting?

What I’m trying to do

I have created a complex HMTL table in obsidian. Everything looks right in the preview. But when I export the table to a PDF, the formatting is wrong, as shown in the picture.

For bullet points, line spacing is inserted which is not there in obsidian directly or even other HMTL renderers such as Firefox etc.

Does anyone have an idea what this could be?
