xaringan演示文稿不显示html小部件，即使编织提供的模板

应该在 xaringan 演示文稿中工作的 HTML 小部件没有在幻灯片上显示/呈现给我。即使我编织提供的模板。作为一个可重复的例子，当我编织时：

---
title: "Presentation Ninja"
subtitle: "?<br/>with xaringan"
author: "Yihui Xie"
institute: "RStudio, PBC"
date: "2016/12/12 (updated: `r Sys.Date()`)"
output:
  xaringan::moon_reader:
    lib_dir: libs
    nature:
      highlightStyle: github
      highlightLines: true
      countIncrementalSlides: false
---

options(htmltools.dir.version = FALSE)

DT::datatable(
  head(iris, 10),
  fillContainer = FALSE, options = list(pageLength = 8)
)

我得到的幻灯片 2 是：

我想在我的演示文稿中包含 DT::datatable() 表。它们目前与其他 RMarkdown 文档很好地结合在一起，例如 ioslides_presentation 和 html_document。这是我的会话信息

我今天刚刚更新了 RStudio：版本 1.4.1103 © 2009-2021 RStudio, PBC "Wax Begonia" (458706c3, 2021-01-06) for macOS

也许也有用：
