r - 将长文本换行到 kable 表列中

Question

我想在我的 kable 表中换行长文本。下面是一个简单的表格示例，其中的列文本太长，需要换行以使表格适合页面。

---
title: "test"
output: pdf_document
---

```{r setup, include=FALSE}
  library(knitr)
```


This is my test

```{r test, echo=FALSE}
test <- data.frame(v1=c("This is a long string. This is a long string. This is a long string. This is a long string. This is a long string.",
                        "This is a another long string. This is a another long string. This is a another long string. This is a another long string. This is a another long string."),
                   v2=c(1, 2))
kable(test)
```

Answer 1

除了很棒的 pander 包之外，另一种解决方案是在 kableExtra 中使用 column_spec。在这种情况下，下面的代码就可以解决问题。

kable(test, "latex") %>%
  column_spec(1, width = "10em")
