css selector "nth-last-child(2)"

Hi all!
I am trying to select the penultimate(the second last) column with the css selector "nth-last-child(2)". The html itself works but in the generated pdf does not work. I tried some of the sandbox projects (https://sandbox.openhtmltopdf.com) but it didn't work there either. I wonder if this is a bug and do you know a workaround for this?

Update
I found this in the logs
```
WARNING:: nth-last-child is not a valid function in this context at line 51. Skipping ruleset.
```

Reproduce the issue in the linked sandbox projects using a table or other markup with :nth-last-child(2), then compare browser rendering with the generated PDF. Start from the warning that nth-last-child is not a valid function and trace the CSS selector handling. Done means the selector works in generated PDFs or a documented workaround is provided.
