Huxtable似乎与Multicl乳胶包装不兼容

我尝试了以下rmarkdown代码,但没有成功:

---
title: 
output: 
  pdf_document:
    latex_engine: pdflatex
header-includes:
   \usepackage{multicol}
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(huxtable)
```
    
```{r echo=FALSE, results='asis'}
m <- rbind(c("A","B"),
           c("C","D"))

ht <- huxtable(m)
```

\begin{multicols}{2}
\begin{enumerate}
\item `r ht`
\item `r ht`
\item `r ht`
\item `r ht`
\end{enumerate}
\end{multicols}

没有表格显示为输出。

任何帮助都将不胜感激。谢谢
