带有 MS-Word 输出的 Bookdown 中的表交叉引用?

问题描述

如何使表格交叉引用在包含所有输出格式 pdf、docx 和 html 的 bookdown 文档中起作用?或者更具体地说，我怎样才能获得适用于 flextables 的表格交叉引用?

How can I make table cross-references work in a bookdown document with all of the output formats pdf, docx, and html? Or maybe more specifically, how can I get table cross-references working for flextables?

下面是一个最小的工作示例.第二个表，使用 kable()，让我几乎一路走到了那里.问题是 docx 输出中的表格渲染完全无法使用(不是在这个 MWE 中，而是在我的实际用例中).我考虑有条件地创建表格，使用 flextable 输出 docx 和 kable 输出 pdf 和 html .flextable 在 docx 输出中看起来不错.但是表引用不起作用！

Below is a minimal working example. The second table, using kable(), gets me almost all the way there. The problem is that the table rendering in docx output is completely unusable (not in this MWE, but in my actual use-case). I considered creating the table conditionally, using flextable for docx output and kable for pdf and html output. flextable looks good in docx output. But the table references don't work!

# Hello World

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

<!--- this tabulates in docx and html output --->
```{r, test01, echo = FALSE, eval = !knitr::is_latex_output()}
mtcars %>%
  head() %>%
  flextable() %>%
  set_caption("My caption!") %>%
  autofit()
```

<!--- this reference does not work in any form of output --->
Trying to reference Table \@ref(tab:test01).

<!--- this tabulates in pdf, docx, html output (but very ugly in docx output) --->
```{r, test02, echo = FALSE}
mtcars %>%
  head() %>%
  knitr::kable(caption = "Need a caption!")
```

<!--- this reference works in pdf, docx, html output --->
Trying to reference Table \@ref(tab:test02).

推荐答案

将 tab.cap="Your Caption" 添加到 knitr 块选项:

Add tab.cap="Your Caption" to the knitr chunk options:

```{r, test03, echo = FALSE, eval = !knitr::is_latex_output(), tab.cap="My flextable caption!"}
mtcars %>%
  head() %>%
  flextable() %>%
  autofit()
```

Reference to Table \@ref(tab:test03).

请参阅此处了解更多表格标题选项.

See here for more table caption options.

这也正确地将数字添加到表格中.如果您希望表格标题采用参考文档中指定的格式，例如表格标题"或Caption"，您可以指定tab.cap.style =Table Caption".

This also adds numbers to tables correctly. If you want your table captions to be in a format designated in your reference document like "Table Caption" or "Caption", you can specify tab.cap.style = "Table Caption".
