knitr to PDFでの複雑なテーブル（書体を変更する）

Rstudio Cloudのリンクはこちらです。

rmakrdownとkableを使ってテーブルをかいてたところ、複雑なテーブルを書く際にkableExtraというパッケージがとても有用だということがわかったのでメモ。

書体を変更できるようにした。

library(knitr)
library(kableExtra)

#Motor Trend Car Road Tests in datasets package is loaded.
dt <- mtcars[1:5, 1:4]

# LaTeX Table
kable(dt, format = "latex", booktabs = T, caption = "Demo Table") %>%
  kable_styling(latex_options = c("striped", "hold_position"),
                full_width = F) %>%
  add_header_above(c(" ", "Group 1" = 2, "Group 2[note]" = 2)) %>%
  add_footnote(c("table footnote"))

タイトルとフッターの書体を変更

 # LaTeX Table
kable(dt, format = "latex", booktabs = T, caption = "\\em{Demo} \\textnormal{Table}", escape =FALSE) %>%
  kable_styling(latex_options = c("striped", "hold_position"),
                full_width = F) %>%
  add_header_above(c(" ", "Group 1" = 2, "Group 2[note]" = 2)) %>%
  add_footnote(c("\\textsc{table} \\textbf{footnote}"), escape=FALSE)

行・列名の書体を変更

# LaTeX Table
colnames(dt)[1] <- "\\textit{mpg}"
colnames(dt)[2] <- "\\textbf{cyl}"
colnames(dt)[3] <- "\\texttt{disp}"
colnames(dt)[4] <- "\\textrm{hp}"

rownames(dt)[1] <- "\\textit{Mazda RX4}"
rownames(dt)[2] <- "\\textbf{Mazda RX4 Wag}"
rownames(dt)[3] <- "\\texttt{Datsun 710}"
rownames(dt)[4] <- "\\textrm{Hornet 4 Drive}"
rownames(dt)[5] <- "\\textsc{Hornet Sportabout}"


kable(dt, format = "latex", booktabs = T, caption = "\\em{Demo} \\textnormal{Table}", escape =FALSE) %>%
  kable_styling(latex_options = c("striped", "hold_position"),
                full_width = F) %>%
  add_header_above(c(" ", "Group 1" = 2, "Group 2[note]" = 2)) %>%
  add_footnote(c("\\textsc{table} \\textbf{footnote}"), escape=FALSE)
