Rmarkdown Html Whitespace

I am trying to add space between two tables and three graphs on an rmarkdown file that is knit into html. I was able to add space between two tables and add a header to the second

Solution 1:

Wrap the following around your first table:

### First Table
<div style="margin-bottom:100px;">
```{r}
# RCODE
```
</div>

Swapping the lines of your table header and the <div.... makes no big difference.
