我想在kable的标题选项中包含一个latex表达式。但是,我收到一个未定义的错误消息。我可以在函数add_header_above
中包含latex表达式,并按预期工作,但是当我在kable(caption=)中尝试相同的表达式时,rmarkdown失败。下面是一个可重现的示例:第一张table很好用,但第二张不行。

LATEX EXPRESSION WORKS FINE
kable(mtcars[1:5,], format = "latex", booktabs = TRUE, caption="Another table with Acrobat") %>%
kable_styling(latex_options = c("striped","HOLD_position")) %>%
add_header_above(c("\\\\Acrobatmenu{GoBack}{\\\\color{blue}{$\\\\updownarrow$}}"=12), align = "r", escape = FALSE)
GET AN ERROR HERE
kable(mtcars[1:5,], format = "latex", booktabs = TRUE, caption="This is a graphic \\\\Acrobatmenu{GoBack}{\\\\color{blue}{$\\\\updownarrow$}}") %>%
kable_styling(latex_options = c("striped","HOLD_position"))
目标是在表格标题旁边得到一个向上和向下的乳胶箭头。我可以通过在表格上添加额外的标题来实现这一点,但我更喜欢在标题旁边得到箭头。见下面的快照:

你必须使用
\\
,而不是\\\\
,来转义kable(caption = "....")
中的LaTeX命令。此外,你必须在标题中使用\protect
命令\Acrobatmenu{GoBack}{\color{blue}{$\updownarrow$}}
