将xtable与longtable选项一起使用时重复标题

问题描述

在生成带有longtable选项的xtable时，是否可以重复顶部行/set标头?

Is there a way to repeat the top row / set headers when generating an xtable with a longtable option ?

例如，如果我有

tableSb <- xtable(df, caption="A Very Long Table", label="ALongTable")
print(tableSb, include.rownames=TRUE, tabular.environment="longtable", floating=FALSE)

这很好，但是当表翻转到新页面时，标题将不会重复.有什么建议吗?

This works fine, but when the tables roll over into a new page the headers are not repeated. Any suggestions ?

推荐答案

为此，您需要使用print函数的add.to.row选项(有关更多信息，请运行?print.xtable).

In order to accomplish this, you'll need to use the add.to.row option of the print function (run ?print.xtable for more information).

尝试一下(改编自 https://r-forge.r-project.org/tracker/?func=detail&atid=4864&aid=1627&group_id=1228 )

addtorow          <- list()
addtorow$pos      <- list()
addtorow$pos[[1]] <- c(0)
addtorow$command  <- c(paste(
  "\\hline \n",
  "\\endhead \n",
  "\\hline \n",
  "{\\footnotesize Continued on next page} \n",
  "\\endfoot \n",
  "\\endlastfoot \n",
  sep=""))
x.big <- xtable(
  x,
  label = "tabbig",
  caption = "Example of longtable spanning several pages")
print(
  x.big,
  tabular.environment = "longtable",
  floating = FALSE,
  include.rownames = FALSE,  # because addtorow will substitute the default row names
  add.to.row = addtorow,     # this is where you actually make the substitution
  hline.after=c(-1))         # because addtorow will substitute the default hline for the first row

解决方案有点笨拙，但至少它将为您提供大量自定义功能.

It's a bit clumsy of a solution, but at least it'll provide you with plenty of customization.
