r - Abbreviate Long Table with Kable/kableExtra?

Question

I'm getting into making HTML documents using Knitr. I would like to include an abbreviated version of my data in the report a la the data.table package. In R, when we use the data.table package, long tables get abbreviated via ellipsis. For instance:

> data.table(iris)
     Sepal.Length Sepal.Width Petal.Length Petal.Width   Species
  1:          5.1         3.5          1.4         0.2    setosa
  2:          4.9         3.0          1.4         0.2    setosa
  3:          4.7         3.2          1.3         0.2    setosa
  4:          4.6         3.1          1.5         0.2    setosa
  5:          5.0         3.6          1.4         0.2    setosa
 ---                                                            
146:          6.7         3.0          5.2         2.3 virginica
147:          6.3         2.5          5.0         1.9 virginica
148:          6.5         3.0          5.2         2.0 virginica
149:          6.2         3.4          5.4         2.3 virginica
150:          5.9         3.0          5.1         1.8 virginica

However, if I try to use kable(iris), the whole table (150 lines) is reproduced. I would like to reproduce the behavior of data.table via kable/kableExtra but I'm not sure how.

At the moment, I'm trying to generate an HTML document, however it would also be nice to know how to do it in LaTeX for future reference.
