| #' Specify Cell format |
| #' |
| #' @description Specify Cell format before it gets into kable |
| #' |
| #' @param x Things to be formated. It could be a vector of numbers or strings. |
| #' @param format Either "html" or "latex". It can also be set through |
| #' `option(knitr.table.format)`, same as `knitr::kable()`. |
| #' @param bold A T/F value to control whether the text of the selected column |
| #' need to be bolded. |
| #' @param italic A T/F value to control whether the text of the selected column |
| #' need to be emphasized. |
| #' @param monospace A T/F value to control whether the text of the selected column |
| #' need to be monospaced (verbatim) |
| #' @param color A character string for column text color. Here please pay |
| #' attention to the differences in color codes between HTML and LaTeX. |
| #' @param background A character string for column background color. Here please |
| #' pay attention to the differences in color codes between HTML and LaTeX. |
| #' @param align A character string for cell alignment. For HTML, possible values could |
| #' be `l`, `c`, `r` plus `left`, `center`, `right`, `justify`, `initial` and `inherit` |
| #' while for LaTeX, you can only choose from `l`, `c` & `r`. |
| #' @param font_size Only if you want to specify font size locally in HTML. |
| #' This feature is not available in LaTeX |
| #' @param angle 0-360, degree that the text will rotate. |
