如果单元格的值大于 80，我需要为单元格着色。例如，给定这个名为 df 的数据框：
dput(df)
structure(list(Server = structure(1:2, .Label = c("Server1",
"Server2"), class = "factor"), CPU = c(79.17, 93), UsedMemPercent = c(16.66,
18.95)), .Names = c("Server", "CPU", "UsedMemPercent"), row.names = c(NA,
-2L), class = "data.frame")
df[2,2] 应为红色。我可以使用 xtable 通过类似这样的方式更改文本的颜色：
df[, 2] = ifelse(df[, 2] > 80, paste("\\color{red}{", round(df[, 2], 2), "}"), round(df[, 2], 2))
如果我这样做并用 kable 打印出表格，它就不会打印出来。有什么想法如何为 kable 输出表中的单元格着色吗？
事实上，你甚至不需要DT or kableExtra如果您需要的只是该单元格的颜色。然而，作为作者kableExtra，不过我确实推荐这个包：P
# What u have now
df <-structure(list(Server =structure(1:2, .Label =c("Server1","Server2"), class = "factor"), CPU =c(79.17, 93), UsedMemPercent =c(16.66,18.95)), .Names =c("Server", "CPU", "UsedMemPercent"), row.names =c(NA,-2L), class = "data.frame")
df[, 2] =ifelse(df[, 2]>80,paste("\\color{red}{",round(df[, 2], 2), "}"),round(df[, 2], 2))
# What you need
kable(df, "latex", escape = F)
