<h1>HTML <col> tag</h1>
<hr />
<h2>Definition and Usage</h2>
<p>Defines the attribute values for one or more columns in a table. You can only
use this element inside a table or a colgroup.</p>
<hr />
<h2>Differences Between HTML and XHTML</h2>
<p>In HTML the <col> tag has no end tag.</p>
<p>In XHTML the <col> tag must be properly closed. </p>
<hr />
<h2>Tips and Notes</h2>
<p><b>Note: </b>The col element is an empty element that contains attributes
only. To create columns, you must specify td elements within a tr element.</p>
<p><b>Tip:</b> Use this element when you want to specify
different attribute values to a column inside a colgroup. Without a col element
a column will inherit all its attribute values from the colgroup.</p>
<hr />
<h2>Example</h2>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<th valign="top" align="left" width="50%">Source</th>
<th valign="top" align="left" width="50%">Output</th>
</tr>
<tr>
<td valign="top">
This example shows a colgroup that has three columns of different
widths:<br />
<table border="1"><br />
<colgroup span="3"><br />
