Adding table classes removes column header

[JasonAizkalns]

Not sure if this expected behavior?

Referring to my StackOverflow Q&A

Consider:

datatable(iris, container = htmltools::tags$table(class="hover row-border"))

What happened to the column headers?

The SO post has been answered, and here is the slightly simplified code with the latest version of DT:

library(DT)
library(htmltools)
datatable(
  head(iris, 20),
  container = tags$table(
    class="stripe row-border",
    tableHeader(iris)
  )
)
