We will investigate this issue.

Is the question confirmed? I have a problem with my writing?

Yes, the question is confirmed, sorry for the delay. Because the table uses "border-collapse: collapse" the border is drawn in separate segments, and a small crack may be visible between the segments when you zoom in the PDF viewer. This crack should not be visible if the PDF file is printed. We will try to remove this crack in a future version of Prince.
