HTML th tag

Example

A simple HTML table, containing two columns and two rows:
<table border="1">
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
</table>


Definition and Usage

The <th> tag defines a header cell in an HTML table.
An HTML table has two kinds of cells:
  • Header cells - contains header information (created with the th element)
  • Standard cells - contains data (created with the td element)
The text in a th element is bold and centered.
The text in a td element is regular and left-aligned.

Browser Support


The <th> tag is supported in all major browsers.

Differences Between HTML and XHTML

The "bgcolor", "height", "width", and "nowrap" attributes of the th element were deprecated in HTML 4.01, and are not supported in XHTML 1.0 Strict DTD.
