title: How to capture cell's output in Databricks notebook
body: <p>I tried using: <code>%%capture my_cap</code>
  but it gives an error:</p>
  <pre><code>TypeError: run_cell() missing 1 required positional argument: 'raw_cell'
  </code></pre>
  <p>So it's unusable :-(  Any other options out there?</p>
