HTML <col> tag
When writing in HTML (hypertext markup language), the <col> tag designates certain properties for each column contained in a <colgroup> element. It is useful when you want to apply formatting to an entire column, rather than each cell individually. The following sections contain information about the <col> tag, including an example of it in use, and related attributes and browser compatibility.
Example of <col> code
<table class="mtable2 tab">
<colgroup>
<col span="1" style="background-color:#c1c1c3">
<col style="background-color:white">
</colgroup>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>March</td>
<td>$200</td>
</tr>
<tr>
<td>April</td>
<td>$300</td>
</tr>
<tr>
<td>May</td>
<td>$250</td>
</tr>
</table>
Example result
Month | Savings |
---|---|
March | $200 |
April | $300 |
May | $250 |
As the HTML code indicates, the entire table has a background color of white and the first column is "painted" grey. The table itself has one of our CSS (cascading style sheets) classes applied to it to improve its appearance.
