如何在markdown中设置knitr :: kable()全局选项以进行重用 [英] How to set knitr::kable() global options in markdown for reuse

问题描述

是否有一种易于使用的方法来设置自定义默认kable()选项，因此无需为每个kable()调用重写它们.

Is there an easy to use way to setup custom default kable() options, so that there is no need in rewriting them for each kable() call.

例如， 我通常的表格样式使用以下代码:

For example, my usual table styling uses following code:

library(kableExtra)
kable(mtcars, booktabs=TRUE, digits= 2) %>% kable_styling(latex_options =c("striped", "scale_down"))

我想设置所有kable() kable_styling选项，以便不带任何参数的kable(mtcars)调用默认为我惯用的表样式.

I would like to set all kable() kable_styling options so that a call to kable(mtcars) with no arguments defaults to my usual table styling.

推荐答案

只需编写您自己的函数即可:

Just write your own function to do that:

kable <- function(data) {
  knitr::kable(data, booktabs = TRUE, digits = 2) %>% 
    kable_styling(latex_options =c("striped", "scale_down"))
}

给它起一个新名字而不是掩盖kable可能会减少混乱；这取决于你.

It might be less confusing to give it a new name instead of masking kable; that's up to you.
