kableExtra 中的度数符号

Question

我正在尝试将度数 (º) 的符号放在使用 kableExtra 制作的表格中。我得到的符号在图片中是一个like：

我只需要符号 (º) 而没有下面的行，如下所示：

我已尝试使用 $^\circ$ 和 \\degree，但我的执行都已停止。

这是我的选择：

这是表格的代码

atm <- read_csv("tablas/atmosfericos.csv") %>%
 select(-Cueva)

kbl(atm, "latex",
 caption = "Atmopheric conditions.\\label{tbl:atm}",
 col.names = c("Punto",
  "CO\\textsubscript{2} (ppm)",
  "T (ºC)",
  "RH"),
 align = c("l", "c", "c","c"),
 label = "atm",
 escape = FALSE, 
 booktabs = TRUE, 
 linesep ="") %>%
 row_spec(0, bold = T) %>%
 kable_paper("hover", full_width = F) %>%
 pack_rows("Cueva de la Iglesia", 1, 6) %>%
 pack_rows("Sistema de Tubo de Lava de Chimalacatepec", 7,12) %>%
 kable_styling(latex_options = "hold_position")
 

非常感谢您的帮助。

Answer 1

命令是\\textdegree{}。

例子：

kbl(data, 
"latex",
 col.names = c("Primer",
  "Sequences 5'-3'",
  "Amplicon (pb)",
  "T\\textsubscript{M}(\\textdegree{}C)*",
  "Referencia"),
 align = c("l", "l", "c","c", "c"),
 label = "primers",
 escape= FALSE, 
 booktabs= TRUE, 
 linesep="")

结果：
