Note: The Colgroup element can only contain COL elements.

Note: The Colgroup element cannot create a table column. To create a column, you must specify the TD element within the TR element.

Tip: Use this element if you need to specify the same property value to a column group.

Tip: If you need to specify property values for one or more columns, use the COL element.

Example：

<table>
<colgroup span= "3" style= "Color:blue" ></colgroup>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
