-## Prepare Your Tables for Both Formats
+## Prepare Your Tables for All Formats
 In most cases, functions in `kable` and `kableExtra` use the same API to accomplish the same styling task in HTML and LaTeX. However, you also need some format specific settings so your tables will look good in both formats. Some common items here include the `booktabs` and `longtable` settings in `kable` and the `bootstrap_options` and `latex_options` in `kable_styling`.

 ## Epub
-Right now, it's impossible to load addition CSS through HTML dependency (due to a setting in rmarkdown). I will file an issue in `rmarkdown` and see if this is something that can be changed. In the mean time, to use bootstrap tables in Epub, you will have to manually load [this stylesheet](https://github.com/haozhu233/kableExtra/blob/master/inst/bootstrapTable-3.3.7/bootstrapTable.min.css) by putting it to a CSS file (such as "style.css") and load it in `_output.yml`.
