Col HTML

HTML <col> Tag

In an HTML table, we can define common column properties for each column within <colgroup> element using the HTML <col> tag. Instead of applying individual style rules for each column cell, it allows to application of common style rules for each column cell. There is no need for an end tag for the HTML <col> tag, however, the XHTML <col> tag does require a closing </col> tag.

Syntax:

<col span=" " style=" ">

Example:

<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
  border: 1px solid brown;
}
</style>
</head>
<body>
 
<table width="400">
<caption>Students Details</caption>
  <colgroup>
  <col style="background-color:lightgray">
  <col span="2" style="background-color:lightyellow">
  </colgroup>
  <tr>
    <th>ID</th>
    <th>NAME</th>
    <th>SUBJECT</th>
  </tr>
  <tr>
    <td>101</td>
    <td>Happy Singh</td>
    <td>English</td>
  </tr>
  <tr>
    <td>201</td>
    <td>Smiley Das</td>
    <td>French</td>
  </tr>
   <tr>
    <td>301</td>
    <td>Joy Gupta</td>
    <td>Hindi</td>
  </tr>
</table>
</body>
</html>
