R在列名称中使用$ sign作为html输出的Markdown kable表

library(knitr)

# 创建一个包含列名称的数据框
data <- data.frame(
  Name = c("John", "Jane", "Mike"),
  Age = c(25, 30, 35),
  Email = c("john@example.com", "jane@example.com", "mike@example.com")
)

# 使用kable函数将数据框转换为Markdown格式的表格
kable(data, format = "html") %>%
  kable_styling()

data <- data.frame(
  `Name <sup>*</sup>` = c("John", "Jane", "Mike"),
  `Age <sub>(years)</sub>` = c(25, 30, 35),
  `Email <a href="mailto:john@example.com">Contact</a>` = c("john@example.com", "jane@example.com", "mike@example.com")
)
