使用 tabularx 环境将表格从 R 导出到 LaTeX

Question

我想在输出中使用 tabularx 环境将长 table 从 R 导出到 LaTeX。我只知道以一种相当老套的方式来做到这一点，将 kableExtra 包与 gsub() 结合起来，以解决 X 列的宽度问题。如果我不使用 gsub()，。 kableExtra 没有定义 X 列的宽度，LaTeX 代码也没有运行。是否有任何软件包可以更无缝地执行此操作？（顺便说一句，我也想把脚注移到“\endfoot”之前，而不是“\endlastfoot”之前。）

我相信 huxtable 软件包可以帮助您完成大部分工作：

library(dplyr)
library(huxtable)

wd <- "1in"
df <- islands %>%
    as_tibble(rownames = "Landmass") %>%
    rename(Area = value) 
ht <- huxtable(df) %>%
    set_table_environment("tabularx") %>%
    set_col_width(2, wd) %>%
    add_footnote(paste(
        "Area shown in thousands of sq mi.", 
        "Includes landmasses with areas larger than 10,000 sq mi."
    )) %>%
    set_caption("Area of World's major landmasses") %>%
    set_label("islands")
print_latex(ht)
