ztable 的 RMarkdown pdf_output |表 |表格

Question

我使用 ztable、xtable 或 htmlTable 包成功生成了表格，没有任何问题。但是，我想知道这些表格是否可以输出为 pdf 文档。当我尝试编织 pdf_output 时，表格没有显示。相反，信息显示为多个字符串。我试过更改 latex 引擎(使用 ztable)和其他方法，但没有成功。

我看过这里:

我也看过小插曲等。

例子(RMarkdown):

---  
output: pdf_document
---

```{r, message = F, results = 'asis'} 
# will throw out Error: pandoc document conversion failed with error 43
library(ztable)
data(iris)
options(ztable.type="latex") 
zt <- ztable(iris[1:5,], caption = "ztable")
zt <- addcgroup(zt,
                cgroup = c("group 1", "group 2"),
                n.cgroup = c(2,3))
print(zt)
```  

```{r, message = F }
# since it's html, will produce text only
library(htmlTable)
data(mtcars)
colnames(mtcars) <- NULL
htmlTable(mtcars[1:5,], caption = "htmlTable",
          cgroup = c("group 1", "group 2"),
          n.cgroup = c(5,6))
```

Answer 1

添加 header-includes:\usepackage{colortbl} 解决了 ztable 的错误。我认为 htmlTable 没有 Latex 引擎。

完整代码:

---  
output: pdf_document
header-includes: \usepackage{colortbl}
---

```{r, message = F, results = 'asis'} 
library(ztable)
data(iris)
options(ztable.type="latex") 
zt <- ztable(iris[1:5,], caption = "ztable")
zt <- addcgroup(zt,
                cgroup = c("group 1", "group 2"),
                n.cgroup = c(2,3))
print(zt)
```  

```{r, message = F }
# since it's html, will produce text only
library(htmlTable)
data(mtcars)
colnames(mtcars) <- NULL
htmlTable(mtcars[1:5,], caption = "htmlTable",
          cgroup = c("group 1", "group 2"),
          n.cgroup = c(5,6))
```
