问题描述
Rmarkdown输出到word将创建一个表而不是两个表
当我在Rstudio中使用Rmarkdown编织Word文档时，预期下面的代码将创建两个独立的表，但是它将创建一个组合表.
The code below is expected to create two independent tables when I knit a Word document using Rmarkdown in Rstudio, but instead it creates one combined table.
期望用两个表创建一个word文档的代码:
Code expected to create a word document with two tables:
---
title: "Untitled"
output: word_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## R Markdown
```{r}
knitr::kable(head(iris))
```
```{r}
knitr::kable(head(iris))
```
但是它只会创建一个:
但是，如果我将echo设置为TRUE，则会得到预期的两个表.当我将同一文档输出到HTML时，它还会创建预期的两个表. 通过单击Rstudio中的编织按钮来创建表.
If, however, I set echo=TRUE, I get the expected two tables. When I output the same document to HTML it also creates the expected two tables. The tables are created by clicking the knit-button in Rstudio.
问题是:如何获得两张桌子，而不是一张?
The question is: How do I get two tables, instead of one?
要澄清:问题不是两个表之间创建的空间很小.问题是创建了一个表.在与此问题相关的图片上，它的确确实是两个表(因为有两个标题)，但实际上是一个一个表.但是阿克斯曼的答案解决了这个问题.我仍然相信这是一个错误，因为在较早版本的knitr中，不必在表之间指定<br><br>，以确保它们不会合并为一个.
To clarify: the problem is not that two tables are created with little space between them. The problem is that one table is created. On the picture attached to this question, it indeed appears to be two tables (because there are two headers), but it is actually one table. But the answer by Axeman solves this. I still believe this is a bug though, because in earlier versions of knitr it was not necessary to specify <br><br> between tables, to ensure that they were not combined into one.
I filed a bug-report, but no one has seen it: https://support.rstudio.com/hc/en-us/community/posts/115008683128-Bug-Two-tables-produced-by-knitr-kable-are-rendered-as-one-in-word-output

推荐答案
在它们之间放置一个HTML注释，可以使表之间的分隔更加清晰.
Put an HTML comment in between, and you get a more clear separation between your tables.
例如
---
title: "Untitled"
output: word_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
## R Markdown
```{r}
knitr::kable(head(iris))
```
<!-- -->
```{r}
knitr::kable(head(iris))
```
如果失败，则可以换行，将<!-- -->替换为<br><br>.
If this fails, you can put a newline instead, replace <!-- --> with <br><br>.
