Denotes a table header cell.

HTML Syntax

<th
   abbr = abbr_header
   colspan = num_columns
   headers = header_cells
   rowspan = num_rows
   scope = 
>

A <th> element’s end tag can be omitted if the <th> element is immediately followed by a <td> or <th> element, or if there is no more content in the parent element.

The <th> element specifies a table cell whose contents are used for column or row headings. <th> elements can only be used inside table rows, or within a tr element.

Browsers usually display the content of <th> elements centered within the cell, and in a bolder font than those of regular table cells.

Although the HTML Standard specifies that <th> end tags are optional and may be omitted, it is safer to always close table headers, as not all browsers support this recommendation, and may produce unexpected results.

The following shows how the th element may be used.

<table>
   <tr><th>This is the header row.</th></tr>
   <tr><td>This is the first row.</td></tr>
   <tr><td>This is the second row.</td></tr>
</table>
