Limit width of HTML table

Question

I'm trying to write a table so that it doesn't expand to the full width of the page. Below is what I have so far, but even though the first columns seem to respect the "width" parameter, the last column expands to the end of the page.

All results I found use CSS, but I am not sure how to do that. I don't know if it's relevant, but I'm writing a Joomla! article.

<table class="zebra" width="300">
  <thead>
    <tr>
      <th style="text-align: left;" width="100">title 1</th>
      <th style="text-align: center;" width="100">title 2</th>
      <th style="text-align: center;" width="100">title 3</th></tr>
  </thead>
  <tbody>
    <tr class="odd">
      <td style="text-align: left;" width="100">content 1</td>
      <td style="text-align: center;" width="100">content 2</td>
     <td style="text-align: center;" width="100">content 3</td>
    </tr>
  </tbody>
</table>
