  <tr><th>
  header 1
  </th><td>
  column 2
  </td></tr>
  </table>

• The default look and feel of a header cell is usually centered with bold text.
• While you can omit the ending tag, tables are easier to read when they are present, and it gives you better control over style tags.
• When using nested tables, if the th tags are not closed, the browsers may become confused as to which table elements go with which table.
