bench result can't be formatted as paged table in a rmarkdown document

[cderv]

Currently this example won't output as one would expect with a tibble

---
title: "test"
output: 
  html_document:
    df_print: paged
---

```{r}
n <- 10L
output <- bench::mark(
   sort(sample.int(n), method = 'radix'),
   sort(sample.int(n), method = 'quick'),
   sort(sample.int(n), method = 'shell')
)
output
```

```{r}
tibble::as_tibble(output)
```

rmarkdown includes a paged table feature for html document to format data.frame. It will be activated in rmarkdown:::knit_print.data.frame. Issue is that this method is currently never called with the current knit_print.bench_mark

library(rmarkdown)
#> Warning: le package 'rmarkdown' a été compilé avec la version R 4.0.3
library(bench)
library(knitr)

n <- 10L
output <- bench::mark(
  sort(sample.int(n), method = 'radix'),
  sort(sample.int(n), method = 'quick'),
  sort(sample.int(n), method = 'shell')
)
output

I believe bench should called NextMethod() instead of using print()

but that is one piece of the issue only. The other one is that the expression column does not print correctly currently...

That means html_notebook and bench does not play well...

I believe we don't have full support yet for vctrs, tibble, pillar. Some stuff must be changed in rmarkdown maybe 🤔
