Question

我正在尝试在pdf的kable列中包含png。我使用rmarkdown :: render编织pdf。我也在使用tinytex和xelatex。图像在html和word doc中都能正常工作，但我不知道为什么它在pdf中不起作用。

图像在电缆外面很好呈现。

这是我的代码：

    ---
    header-includes:
    - \usepackage{booktabs}
    - \usepackage{longtable}
    - \usepackage{array}
    - \usepackage{multirow}
    - \usepackage{wrapfig}
    - \usepackage{float}
    - \usepackage{colortbl}
    - \usepackage{pdflscape}
    - \usepackage{tabu}
    - \usepackage{threeparttable}
    - \usepackage{threeparttablex}
    - \usepackage[normalem]{ulem}
    - \usepackage{makecell}
    - \usepackage{xcolor}
    - \usepackage{fontspec}
    - \setmainfont{Calibri}
    output: 
      pdf_document:
        latex_engine: "xelatex"

```{r message=FALSE, warning=FALSE, results='asis'}
    library(knitr)
    library(rmarkdown)
    library(kableExtra)
    up <- knitr::include_graphics("up-arrow.png", dpi = 100)
    down <- knitr::include_graphics("C:/Users/datimmer/Desktop/Notes/down-arrow.png")
    up
    down
    cat("![](",'C:/Users/datimmer/Desktop/Notes/up-arrow.png)',")")
    '![](C:/Users/datimmer/Desktop/Notes/up-arrow.png)'
    paste0('![test](C:/Users/datimmer/Desktop/Notes/up-arrow.png)')
    df <- data.frame(
      stock = c('Apple','Amazon','Microsoft','Tesla'),
      value = c(300,200,150,250),
      difference = c(50,-10,20,-15)
    )
    df$trend <- ifelse(df$difference >0,
                       sprintf('![](%s)', 'C:/Users/datimmer/Desktop/Notes/up-arrow.png'),
                       knitr::include_graphics("C:/Users/datimmer/Desktop/Notes/down-arrow.png")
                      )

    knitr::kable(df, 'latex')

这是我的pdf与此代码相似的样子，因为您可以看到png在电缆外面很好地呈现。
