Vertical align kable's column name

问题:

Suppose the next example:

library(knitr)
library(kableExtra)

df <- data.frame(a = letters[1:10], b = 1:10)

names(df) <- c("This is a looooooong title, I don't know how to handle this... Also, I'm trying to extend this title even more... This column name will be used to compute vertical space","I want to align vectically this column name")

df %>% kable(format = 'latex', linesep = "", align = 'c') %>% kable_styling(full_width = T)

How can align vertically the second column name?

回答1:

I am not sure if there is an easier way, but you can go with the multirow package:

---
title: "Test Book"
header-includes:
  - \usepackage{multirow}
author: "therimalaya"
output: 
  pdf_document:
    keep_tex: yes
---

# Hello World


```{r, error = TRUE, echo = T}
library(knitr)
library(kableExtra)

df <- data.frame(a = letters[1:10], b = 1:10)
names(df) <- c("This is a looooooong title, I don't know how to handle this... Also, I'm trying to extend this title even more... This column name will be used to compute vertical space","\\multirow{1}{*}[0pt]{I want to align vectically this column name}")

df %>% kable(format = 'latex', linesep = "", align = 'c', escape = F) %>% kable_styling(full_width = T)
```
