title: TypeError: 'Styler' object is not subscriptable
body: <p>I can access a subset of columns like this:</p>
  
  <pre><code>df[[5, 6]]
  </code></pre>
  
  <p>..but after the following line to push text to the left and make it more readable:</p>
  
  <pre><code>df = df.style.set_properties(**{'text-align': 'left'})
  </code></pre>
  
  <p>..the same command produces an error:</p>
  
  <pre><code>TypeError: 'Styler' object is not subscriptable
  </code></pre>
  
  <p>Is this expected behaviour, or do you need to use some trick now to get to the columns?</p>
  
  <p>Am using Python 3.7.6 and Pandas 1.0.3</p>
