+> **Key Update**: I understand the need of doing conditional formatting and the previous solution `cell_spec` is relatively hard to use. Therefore in kableExtra 1.2, I improved the functionality of `column_spec` so it can take vectorized input for most of its arguments (except `width`, `border_left` and `border_right`). It is really easy right now to format a column based on other values.

+You can still use the `spec_***` helper functions to help you define color. See the documentation [below](#visualize-data-with-viridis-color).

 ## Row spec
 Similar with `column_spec`, you can define specifications for rows. Currently, you can either bold or italicize an entire row. Note that, similar to other row-related functions in `kableExtra`, for the position of the target row, you don't need to count in header rows or the group labeling rows.

 # Cell/Text Specification
+
+>**Key Update: As said before, if you are using kableExtra 1.2+, you are now recommended to used `column_spec` to do conditional formatting**. 
+
 Function `cell_spec` is introduced in version 0.6.0 of `kableExtra`. Unlike `column_spec` and `row_spec`, **this function is designed to be used before the data.frame gets into the `kable` function**. Comparing with figuring out a list of 2 dimensional indexes for targeted cells, this design is way easier to learn and use, and it fits perfectly well with `dplyr`'s `mutate` and `summarize` functions. With this design, there are two things to be noted:
 * Since `cell_spec` generates raw `HTML` or `LaTeX` code, make sure you remember to put `escape = FALSE` in `kable`. At the same time, you have to escape special symbols including `%` manually by yourself
 * `cell_spec` needs a way to know whether you want `html` or `latex`. You can specify it locally in function or globally via the `options(knitr.table.format = "latex")` method as suggested at the beginning. If you don't provide anything, this function will output as HTML by default.
