How can you display only two columns, email and WhatsApp, in a data table?

To display only the email and WhatsApp columns, you need to select those fields from your data source and bind them to the UI component. In SQL you would write:

SELECT email, whatsapp FROM users;

If you are using a front‑end framework like React, you would map over the data array and render only those two properties:

{users.map(u => (
  <tr key={u.id}>
    <td>{u.email}</td>
    <td>{u.whatsapp}</td>
  </tr>
))}

The key idea is to filter the data at the source (SQL or API) or in the rendering logic so that only the desired columns appear in the table.
