Knitting tables with kable

The kable function from the knitr package allows to display nicely formatted tables using R Markdown, as explained here. I recently encountered unexpected behaviour of kable when calling it from lapply or a function, which led to this post on StackOverflow. The answers were very detailed and enlightening, and I invite you to read them. They could be summarized in two points: be aware of side-effects, and prefer cat (with new lines) to print.
