这种面向降价的解决方案是否适合您?
```{r, results='asis'}
kable(head(iris), caption = '**I want this in Bold**') %>%
kableExtra::kable_styling(bootstrap_options = c("striped", "hover", "condensed","responsive"))
```
对于html-output 这应该可以工作:
```{r, results='asis'}
kable(head(iris), caption = '<b>I want this in Bold</b>', format = 'html') %>%
kableExtra::kable_styling(bootstrap_options = c("striped", "hover", "condensed","responsive"))
```
对于pdf-output 这应该可以工作:
```{r, results='asis'}
kable(head(iris), caption = '\\textbf{I want this in Bold}', format = 'latex') %>%
kableExtra::kable_styling(bootstrap_options = c("striped", "hover", "condensed","responsive"))
```
