Describe the enhancement requested

Deno has officially supported Jupyter, and jupyter output can be customized by defining a [Symbol.for("Jupyter.display")] method in the class.

For example, the following code displays a dataframe.

{ [Symbol.for("Jupyter.display")]() { return { // HTML output "text/html": `  <table border="1" class="dataframe">  <thead>  <tr>  <th>name</th>  <th>age</th>  </tr>  </thead>  <tbody>  <tr>  <td>Alice</td>  <td>22</td>  </tr>  <tr>  <td>Bob</td>  <td>24</td>  </tr>  </tbody>  </table>`, } }

The output is like:

This can be helpful for interactive data exploration.
