+The following feature is introduced in `kableExtra` 0.3.0.
+
+# Repeat Header in longtable
+In this release, a new option `repeat_header` was introduced into `kable_styling`. It will add header rows to longtables spanning multiple pages. For table captions on following pages, it will append *"continued"* to the caption to differentiate. If you need texts other than *"(continued)"* (for example, other languages), you can specify it using `kable_styling(..., repeat_header_text = "xxx")`.

+ add_header_above(c(" ", "Group 1" = 5, "Group 2" = 6)) %>%
+ kable_styling(latex_options = c("repeat_header"))
