 Note: `kableExtra` was using `xcolor` for alternative row color before 1.0. However, the recent updates in `fancyvbr` causes a clash in `xcolor` option. Therefore, we removed the `xcolor` dependency in version 1.0 and started to rely on `colortbl` completely. If you experience any issues, please report on github.
