title: Grid Layout in an R Markdown
body: <p>Is there a clean way to "tile" or create some sort of table-like layout in rmarkdown? For example, in RShiny you can setup a grid of sorts and then place elements (e.g., text, tables, plots, etc...) in these slots to really control your look. I am open to the output being in HTML, Word, or PDF if markdown is not the best way. As an example, consider this file:</p>
  
  <pre><code>---
  title: "Test File"
  output: html_document
  ---
  
  ## R Markdown
  
  How do put these side-by-side?
  
  ```{r text, echo=FALSE}
  summary(cars)
  ```
  
  ```{r plot, echo=FALSE}
  plot(speed ~ dist, cars)
  ```
  </code></pre>
  
  <p>Can I place the <code>summary()</code> output next to the <code>plot()</code> output? What if I wanted to go three wide: <code>plot()</code> | <code>summary()</code> | <code>summary</code>?</p>
  
  <p>I'd be open to another format / construct as well. I have tried <code>officer</code> but struggle to get this type of alignment in Word to work.</p>
