RMarkdown Beamer中先绘图后用etable+adjustbox表格不显示求助

用fixest的feols()做回归分析，etable()生成表格嵌入Beamer演示文稿，依赖LaTeX的adjustbox包让宽表格适配页面宽度。但幻灯片中先插入ggplot图表后，带adjustbox的表格无法显示；移除前置图表后，表格又能正常渲染。

可复现代码如下：

YAML头部 #

title: "Teste"
output: beamer_presentation

  - \usepackage{booktabs}
  - \usepackage{longtable}
  - \usepackage{array}
  - \usepackage{multirow}
  - \usepackage{wrapfig}
  - \usepackage{float}
  - \usepackage{colortbl}
  - \usepackage{pdflscape}

R代码块 #

{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(fixest)
library(tidyverse)
library(tinytex)

{r pressure}
pressure%>%
  ggplot(aes(x=temperature,y=pressure))+
  geom_point()

{r cars, results = 'asis'}
ols=feols(speed~dist,data=cars)

etable(ols,ols,ols,ols,ols,ols,style.tex = style.tex(adjustbox = T),postprocess.df = pandoc.table.return,tex=T)

方案1：给图表添加固定位置参数 #

图表默认的浮动环境会干扰后续LaTeX代码渲染，给ggplot代码块加fig.pos='h'强制图表固定在当前位置：

{r pressure, fig.pos='h'}
pressure%>%
  ggplot(aes(x=temperature,y=pressure))+
  geom_point()

方案2：移除postprocess.df参数 #

postprocess.df = pandoc.table.return会让etable先转成pandoc格式再转LaTeX，和adjustbox的原生LaTeX输出冲突，直接删除该参数即可：

{r cars, results = 'asis'}
ols=feols(speed~dist,data=cars)

etable(ols,ols,ols,ols,ols,ols,style.tex = style.tex(adjustbox = TRUE), tex = TRUE)

方案3：手动包裹adjustbox环境 #

如果前两种方法无效，直接手动用adjustbox包裹etable生成的表格，绕开自动生成的格式冲突：

{r cars, results = 'asis'}
ols=feols(speed~dist,data=cars)
# 生成表格内容但不直接打印
tab_content <- etable(ols,ols,ols,ols,ols,ols, tex = TRUE, print = FALSE)
# 手动添加adjustbox包裹代码
cat("\\begin{adjustbox}{width=\\textwidth}\n", tab_content, "\n\\end{adjustbox}", sep = "")
