如何在rmarkdown的kable表中更改单元格的字体(粗体/斜体)? [英] How to change fontface (bold/italics) for a cell in a kable table in rmarkdown?

问题描述

有没有一种方法可以在rmarkdown中格式化表格中的单个单元格?我正在使用kable生成表，如下所示:

Is there a way to format a single cell in a table in rmarkdown? I am using kable to generate a table as follows:

library(knitr)
kable(data.frame(c('a','b','c'),c(1,2,3)))

我希望在最后一行加粗"c"，并在表格末尾添加一条水平线.有指针吗?

I wish to bold "c" in the last row and also add a horizontal line at the end of the table. Any pointers?

推荐答案

用pander突出显示单元格，行或列很容易

Highlighting cells, rows or columns with pander is pretty straightforward:

> df <- data.frame(c('a','b','c'),c(1,2,3))
> emphasize.strong.cells(which(df == 3, arr.ind = TRUE))
> pander(df)

-------------------------------
 c..a....b....c..   c.1..2..3. 
------------------ ------------
        a               1      

        b               2      

        c             **3**    
-------------------------------

但是在表格中添加水平线超出了 markdown表格规范的范围

But adding horizontal line to the table is out of the scope of markdown table specifications.
