提高可见性/增加 table 中一列的字体大小：使用 kableextra 生成的 pdf 输出

Question

我正在使用 rmarkdown 生成 pdf 文档。

我使用以下代码生成 table：

YAML:

---
title: "Queries"
header-includes:
- \usepackage{pdflscape}
- \usepackage{longtable}
- \usepackage{xcolor}
output: 
  pdf_document:
    toc: false
    latex_engine: xelatex
mainfont: Arial
---

{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(dplyr)
library(kableExtra)
library(stringr)
library(readxl)

{r query}
df <- data.frame(a =  rep("text", 3),
                 b = c("\uparrow", " \leftrightarrow", "\downarrow"),
                 c = rep(" lots more text ...", ))

df%>%
  kbl(longtable = FALSE, escape = F, booktabs =  T, align = "c")%>%
  column_spec(1, width =  "8em")%>%
  column_spec(3, width = "9em")%>%
  column_spec(2, bold = TRUE, color = "red")%>%
  kable_styling(font_size = 8)

输出如下所示：

我真的很想让第 2 列 b 更显眼，最好是 仅增加该列的字体大小 ，从而增加箭头的大小.这是可能的还是有其他方法可以产生相同的效果？

Answer 1

您可以为箭头添加所需的字体大小：

---
title: "Queries"
header-includes:
- \usepackage{pdflscape}
- \usepackage{longtable}
- \usepackage{xcolor}
output: 
  pdf_document:
    toc: false
    latex_engine: lualatex
    keep_tex: true
mainfont: Arial
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(dplyr)
library(kableExtra)
library(stringr)
library(readxl)
```


```{r query}
df <- data.frame(a =  rep("text", 3),
                 b = c("\LARGE\uparrow", " \LARGE\leftrightarrow", "\LARGE\downarrow"),
                 c = rep(" lots more text ...", ))

df%>%
  kbl(longtable = FALSE, escape = F, booktabs =  T, align = "c")%>%
  column_spec(1, width =  "8em")%>%
  column_spec(3, width = "9em")%>%
  column_spec(2, bold = TRUE, color = "red")%>%
  kable_styling(font_size = 8)
```
