13.3 summarytools
由于很多 summarytools 中的函数往往直接生成 markdown 代码，为了在 rmarkdown 正确美观的呈现它们需要同时设置 summarytools 中和 knitr 中的一些全局选项：（详细可见Recommendations for Using summarytools With Rmarkdown）。
st_options(bootstrap.css = FALSE, # Already part of the theme so no need for it
plain.ascii = FALSE, # One of the essential settings
style = "rmarkdown", # Idem.
dfSummary.silent = TRUE, # Suppresses messages about temporary files
footnote = NA, # Keeping the results minimalistic
subtitle.emphasis = FALSE) # For the vignette theme, this gives
# much better results. Your mileage may vary.
st_css() # This is a must; without it, expect odd layout, especially with dfSummary()
#> <style type="text/css">
