I want to create dynamic sections in my R markdown document. For this, I use R chunks with the asis output type. The chunks contain tables created by the reactable package.
I cannot get the tables to print when I create them in a for-loop. I know that one usually must wrap plots or the like within print() in loops, but that had no effect in my case.
How can I get the tables to print?

title: "Test"
author: "Test"
date: "29 11 2021"
output: html_document

```{r include=FALSE}
library(reactable)
```
```{r results='asis', echo=FALSE}
cat("\n\n## My header 1 \n\n")
reactable(data.frame(test = rnorm(3))) ## This works
```
```{r results='asis', echo=FALSE}
for (i in 1:3) {
cat("\n\n## My header ", i+1, "\n\n")
print(reactable(data.frame(test = rnorm(3)))) ## shows nothing
}
```
I just found out, that reactable uses htmlwidgets under the hood. So one can wrap the result in shiny::tagList() to display it in a loop.

}
