wrap long text in kable table column

Question

I would like wrap long text in my kable table. Here is a simple example of a table with column text that is too long and needs to be wrapped for the table to fit on the page

Answer 1

An alternative solution other than the awesome pander package is to use column_spec in kableExtra. In this case, the following code will do the trick.

kable(test, "latex") %>%
  column_spec(1, width = "10em")

Answer 2

I've created the pander package to produce markdown tables in a flexible way. By default, it will split cells with long string to 30 chars, but there are a bunch of global options and fn arguments to override that, enable hyphenation and other tweaks. Quick demo:

> pander::pander(test)

-----------------------------------
              v1                v2

This is a long string. This is  1

    This is a long string.         

This is a another long string.  2
