更改KableExtra中标题的大小？

Question

我尝试过许多技术(主要是围绕caption，以便在使用KableExtra时更改标题(又名字幕)的大小)。

最小可重现性示例

下面是一个简单的例子：

library(knitr)
library(kableExtra)

iris %>%
  head %>%
  kable(
    table.attr = "style = \"color: black;\"", 
    caption = "<span style='font-size:20'>A lovely title</span>"
    ) %>%
  kable_styling("striped", full_width = T) 

但是标题大小并没有改变：

Answer 1

Span以3种不同的方式接受CSS font-size。运行以下示例以查看它们的运行情况：

象素

library(knitr)
library(kableExtra)


iris %>% 
  head %>% 
  kable(
    table.attr = "style = \"color: black;\"", 
    caption = "<span style='font-size:20px'>A lovely title</span>"
    ) %>% 
  kable_styling("striped", full_width = T) 

百分比

iris %>% 
  head %>% 
  kable(
    table.attr = "style = \"color: black;\"", 
    caption = "<span style='font-size:200%'>A lovely title</span>"
    ) %>% 
  kable_styling("striped", full_width = T) 

“小”、“大”等。

iris %>% 
  head %>% 
  kable(
    table.attr = "style = \"color: black;\"", 
    caption = "<span style='font-size:small'>A lovely title</span>"
    ) %>% 
  kable_styling("striped", full_width = T)
