title: Data Table Display in Google Colab not adhering to number formats
body: <p>I want to set the precision for floats when using <a href="https://colab.research.google.com/notebooks/data_table.ipynb" rel="nofollow noreferrer">Colab Data Table Display</a></p>
  
  <p>I'm finding that the code below works as intended in the native pandas dataframe display, but it does not work for the otherwise snazzier Data Table display. </p>
  
  <pre><code>import pandas as pd
  df = pd.DataFrame(np.random.rand(15, 4), columns=list('ABCD'))
  
  df.style.format("{:.2%}")
  </code></pre>
  
  <p>or alternatively for the last line above</p>
  
  <pre><code>pd.options.display.float_format = '{:,.2f}'.format
  </code></pre>
  
  <p>The <a href="https://colab.research.google.com/notebooks/data_table.ipynb" rel="nofollow noreferrer">Colab demo</a> for this feature also displays floats with ugly levels of precision, but I am hoping there's a way to control formatting. Any guidance greatly appreciated.</p>
