```{r message=FALSE, results = 'asis', echo=FALSE, warning=FALSE, fig.width=12, fig.height=10}
library(xtable)

glossary2<-data.frame(names=letters[1:4],definition=c("very long long long text very long long long text very long long long text very long long long text","very long long long long long text","very long long long long long long text","very long long long text"),include=c(NA,"YES",NA,"NO"))
glossaryprin<-xtable(glossary2,label="tab:codebook",caption="glossary")

align(glossaryprin)<-"lp{2in}p{3in}p{1in}" #here is the change
print(glossaryprin,tabular.environment="longtable",floating=FALSE,size="\\fontsize{30pt}{10pt}\\selectfont")
```

我可以在xtable输出表之外删除{和}吗？
