How do you format a table in pdf using kable function? Because my output table width exceeds the width of the pdf. Here is an example:
---
output: pdf_document
---
```{r}
df <- cbind(mtcars[1:5,], mtcars[1:5,])
knitr::kable(df)
```
回答1:
One option is to use kable_styling from the kableExtra package. The option latex_options="scale_down" will fit the table within the paper margins. See the vignette for detailed examples on all of the formatting options.

output: pdf_document

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(knitr)
library(kableExtra)
```
```{r}
kable(cbind(mtcars[1:5,], mtcars[1:5,]))
```
```{r}
kable(cbind(mtcars[1:5,], mtcars[1:5,]), format="latex", booktabs=TRUE) %>%
kable_styling(latex_options="scale_down")
```
