自動換行編織器xtable（R /乳膠）

Question

我正在試圖在knitr生成的PDF文檔的每一行用長句子做xtable。

我試過：

<<echo=F,results="asis",command=NA>>= 
df<-c("This is a very very very very very very very very very very very very very very very very very very very very long line", 
"Another very very very very very very very very very very very long line") 
df<-as.data.frame(df) 
xtab <- xtable(df) 
print.xtable(xtab,sanitize.text.function=function(x){x}) 
@ 

但我的結果是：

正如你所看到的。我的xtable溢出了頁面，因爲我的行太長了。有人能幫我嗎 ？

PS：我不能使用{tabular}，因爲我的數據框的長度取決於閃亮的應用程序用戶的輸入。

看一看對齊功能：

<<echo=FALSE,results=tex>>= 
library(xtable) 
df<-c("This is a very very very very very very very very very very very very very very very very very very very very long line", 
"Another very very very very very very very very very very very long line") 
df<-as.data.frame(df) 
xtab <- xtable(df) 
align(xtab) <- "|lp{6cm}|" 
print.xtable(xtab,sanitize.text.function=function(x){x})

你可以用它來改變像你的列對齊會爲任何其他LaTeX的表。這些資源可以對你有所幫助：
