To create a zebra-striped table using inline styles, apply different background colors to alternating rows manually.
Example:
<table border="1">
  <tr style="background-color: #f2f2f2;">
    <th>Name</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Alice</td>
    <td>25</td>
  </tr>
  <tr style="background-color: #f2f2f2;">
    <td>Bob</td>
    <td>30</td>
  </tr>
  <tr>
    <td>Charlie</td>
    <td>28</td>
  </tr>
</table>
