kables() function not documented? how to place tables 'bottom to top' instead of side by side?

[r-scotti]

Hello, greatly appreciated book.
I am writing to put a general issue while asking a more specific question.

1. I could not find any documentation for the 'knitr::kables()' function. I am trying to guess how it works looking at the code. Is the documentation missing?
2. Using Quarto with format: pdf, I would like to have a couple of tables printed on the same page. Using knitr::kables(list(kable(tab1), kable(tab2))) places the two side by side. The tables are too wide to fit side by side and the rendering halts. I need to print them one above the other. How could I proceed?
   Many thanks, Roberto
