HTML th tag

When writing in HTML, the <th> tag is used to designate a cell that is a header for a group of cells within a table. It is useful for storing information about a set of rows or columns. The following sections contain information about the <th> tag, including an example of it in use, as well as related attributes and browser compatibility.

Tip

More advanced tables may also include the <caption>, <col>, <colgroup>, <tbody>, <tfoot>, or <thead> elements.

Example of <th> code

<table class="mtable2 tab">
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr class="tcw">
<td>March</td>
<td>$200</td>
</tr>
<tr class="tcw">
<td>April</td>
<td>$300</td>
</tr>
<tr class="tcw"> <td>May</td>
<td>$250</td>
</tr>
</table>

Example result

Month Savings
March $200
April $300
May $250

We have added a few of our own classes to the table using CSS; this action allows us to improve its appearance.

Attributes

Within an HTML tag, an attribute dictates certain aspects of an HTML element. Attributes are made up of a name and value pair; all tags support standard attributes. The following table shows all of the current unique HTML attributes for the <th> tag, as well as a description of each.

Attribute Description
abbr Designates an abbreviated version of the content within a header cell.
colspan Designates how man columns a header cell should span.
headers Designates one or more header cells to which a certain cell has relation.
rowspan Designates how man rows a header cell should span.
scope Designates whether a header cell is a header for a column, row, or group of columns or rows.
sorted Designates the sorting direction of a column.

Deprecated attributes

A deprecated attribute is one that may function currently but is not supported in going forward. While the attribute may work with the current version of HTML, it will eventually be phased out. It is better to avoid using these attributes to help future-proof your website.
