The <colgroup> tag is a group of one or more than one column in a table. It sets the style for all the columns.
Following is the attribute of the <colgroup> tag −
- span − Number of columns a column group should span is set with span attribute
Example
Let us now see an example to implement the <colgroup> tag −
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 2px solid black;
}
</style>
</head>
<body>
<h2>Result</h2>
<table>
<colgroup>
<col span="3" style="background-color:gray;">
<col style="background-color:orange;">
</colgroup>
<tr>
<th>Id</th>
<th>Name</th>
<th>Percentage</th>
<th>Rank</th>
</tr>
<tr>
<td>009</td>
<td>Tom</td>
<td>98</td>
<td>1</td>
</tr>
<tr>
<td>011</td>
<td>Kieron</td>
<td>97</td>
<td>2</td>
</tr>
<tr>
<td>039</td>
<td>Gayle</td>
<td>95</td>
<td>3</td>
</tr>
<tr>
<td>017</td>
<td>Shaun</td>
<td>92</td>
<td>4</td>
</tr>
<tr>
<td>009</td>
<td>Kane</td>
<td>91</td>
<td>5</td>
</tr>
<tr>
<td>025</td>
<td>Steve</td>
<td>87</td>
<td>6</td>
</tr>
<tr>
<td>013</td>
<td>Jack</td>
<td>85</td>
<td>7</td>
</tr>
<tr>
<td>023</td>
<td>Tim</td>
<td>84</td>
<td>8</td>
</tr>
</table>
</body>
</html>Output
This will produce the following output −
In the above example, we have set style for more than one column −
<colgroup> <col span="3" style="background-color:gray;"> <col style="background-color:orange;"> </colgroup>
We have set the gray background color style for the first 3 columns above in the <colgroup> element −
<col span="3" style="background-color:gray;">
The rest of the column(s) is set to orange background color style −
<col style="background-color:orange;">
