It seems the API allows for renaming columns within options > columnDefs (see here). However, passing name as an argument doesn’t seem to take. Does DT not support this or am I doing something wrong? I don’t want to rename the columns upstream; I just want to know if I’m missing something in the documentation.

Here the searchable argument is used (the mpg column search is greyed out) but the name argument is not applied:

mtcars |>
  DT::datatable(
    filter = "top",
    options = list(
      columnDefs = list(
        list(targets = 1, name = "x", searchable = FALSE)
      )
    )
  )
