How to make a collapsible or foldable table in Rmarkdown

Question

Hi I want to present some data with group of people using rmarkdown

some table is large, say 100+ lines, and not all the people want to view so much detail, they may only need to check first 20 lines of the table

So is there a way to show at the beginning 20 rows of the table, but if they want they can unfold the table to see the rest part of the table?

Answer 1

You can use datatable from DT package.

For example:

DT::datatable(mtcars, options = list(pageLength = 20))

Shows only first 20 lines. And to show more lines you can change Select N entries.
