knitr - 在 bookdown :html_document2 中没有使用 pander 的表格编号

Question

当与 bookdown::html_document2 一起使用时，pander 不包括表格编号。我错过了一些选择吗？

# Chapter 1

```{r}
library(knitr)
library(pander)
# Table 1.1
kable(head(iris), caption = "Iris with kable")
# Another Table 1.1 (ok, same chunk = same table)
kable(head(mtcars), caption = "Mtcars kable")
```

```{r}
# No table number
pander(head(iris), caption = "Iris with pander")
```

```{r}
# Table 1.2
kable(head(mtcars), caption = "Mtcars kable")
```

If you decide to use other R packages to generate tables, you have to make sure the label for the table environment appears in the beginning of the table caption in the form (\#label) (again, label must have the prefix tab:).

这里的原因是 pander::pander()不产生正确的 (\#tab:***) .你可以向 的作者报告这个bug驯鹿 .
kable(head(iris), caption = "Iris with kable")
