Rmarkdown output to word creates one table instead of two
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.
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))
```
But it only creates one:
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.
The question is: How do I get two tables, instead of one?
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

回答1:
Put an HTML comment in between, and you get a more clear separation between your tables.
E.g.
---
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))
```
If this fails, you can put a newline instead, replace <!-- --> with <br><br>.
