Translate perpesptive perspective table pager options ('rows')

What is the correct translation key for the word ‘rows’ in the perspective table pager? I tried ‘rows’ and ‘%d rows’ without success.

The Perspective table component doesn’t yet support translation - it was left out of the initial push to bring translation to Perspective components because the table components were going through a major refactor.

Any update on this topic?
The ‘rows’ and ‘Empty Data Source’ texts are still not translatable in 8.1.1
