我在rMarkdown中编写文档,我需要在生成PDF之前格式化表格。问题是我在使用kable
命令添加的add_headers_above
标头中插入新行时遇到问题。
目前文本"月(人)" - 这是使用该命令添加的第一个标题 - 显示为一行。我想打破它,以便在"月"之间插入一个新行。和"(人)"。
动机只是保存水平页面空间,以便我可以在一张A4纸上按尺寸调整两张桌子。
我已尝试在\n
命令中加入add_headers_above
:
[...] %>%
add_header_above(c(" ", 'Month \n (persons)' = 1, "TTY \n (persons)" = 1, "TTY \n (% chg.)" = 1))
但那还没有奏效。

目前,您必须自己编写一些原始乳胶代码。
正如https://tex.stackexchange.com/questions/2441/how-to-add-a-forced-line-break-inside-a-table-cell建议的答案所示,您可以尝试使用makecell
包。为此,您可以使用kableExtra::usepackage_latex()
加载乳胶包,然后通过在escape = F
中设置add_header_above
来破解它。
usepackage_latex("makecell")
kable(df, format = 'latex', booktabs = T, align = 'r') %>%
kable_styling(full_width = F, font_size = 8) %>%
row_spec(row = 9, bold = TRUE) %>%
add_header_above(c(" ",
'\\\\thead{Month\\\\\\\\(persons)}' = 1,
"\\\\thead{TTY\\\\\\\\(persons)}" = 1,
"\\\\thead{TTY\\\\\\\\(\\\\% chg.)}" = 1),
escape = F)
<强>更新强>
别介意上面的乳胶混乱,我让它在kableExtra
的开发版中工作。现在你做了
library(kableExtra)
mtcars[1:5, 1:5] %>%
kable("latex", booktabs = T) %>%
add_header_above(c(" ", "aa\na" = 2, "bbb" = 3))

这很难,因为LaTeX不喜欢表格单元格中的换行符 - 例如https://tex.stackexchange.com/questions/2441/how-to-add-a-forced-line-break-inside-a-table-cell了解这有多难。你几乎肯定会更好地为&#34;(人)和#34;插入一个单独的行。等等。
