How to include groups of table columns in HTML
In HTML, you can use the <colgroup> and <col> elements to group and style columns within a table. This approach allows you to apply common styling or formatting to a specific group of table columns.
By using these elements, you can enhance the structure and presentation of your tables.
- The <colgroup> element is used to group table columns together. It acts as a container for one or more <col> elements.
- Inside the <colgroup> element, you define <col> elements to represent individual columns or column groups. In the code snippet, we have two <col> elements.
- The span attribute in the first <col> element specifies the number of consecutive columns to include in the group. In this case, we set it to 2, so it includes the first two columns.
- You can apply styling to the <col> elements using the style attribute. In the example, we set the background color of the first two columns to light blue and the third column to light green.
- The <colgroup> and <col> elements are placed before the <tr> (table row) and <th> (table header) or <td> (table data) elements. The browser will apply the specified styling to the corresponding columns in the table.
