The HTML <tbody> tag is a fundamental part of table structure in web development. It is used to group the body content of a table, helping to distinguish the main data from the header (<thead>) and footer (<tfoot>) sections. By using the <tbody> tag, developers can make table content more organized, readable, and accessible, both for users and search engines.
The <tbody> tag does not change how the table is rendered by default but plays a critical role in defining the table's structure, especially when combined with other tags like <thead> and <tfoot>.
Syntax of the <tbody> Tag
The syntax of the <tbody> tag is straightforward. It is placed within the <table> element and wraps around the rows of the table's body content:
<table>
<thead>
<!-- Table header content -->
</thead>
<tbody>
<!-- Table body rows -->
</tbody>
<tfoot>
<!-- Table footer content -->
</tfoot>
</table>
The <tbody> tag contains one or more <tr> (table row) elements, which in turn include <td> (table data) elements that define the individual cells of the table.
Attributes of the <tbody> Tag
The <tbody> tag supports several global attributes that allow for styling and identification, which are common to all HTML elements.
Attribute | Description |
---|---|
class | Specifies a class name for the <tbody> element for CSS styling. |
id | Assigns a unique identifier to the <tbody> for reference in JavaScript or CSS. |
style | Allows inline CSS styles to be applied directly to the <tbody> content. |
lang | Defines the language of the table body’s content. |
data-* | Allows embedding custom data attributes for use in JavaScript applications. |
These attributes provide flexibility, allowing developers to control the appearance and behavior of the table body.
Examples of HTML <tbody> Tag
Example 1: Simple Table with <tbody>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Simple Table Example</title>
</head>
<body>
<table border="1">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Occupation</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>25</td>
<td>Engineer</td>
</tr>
<tr>
<td>Alice</td>
<td>30</td>
<td>Teacher</td>
</tr>
</tbody>
</table>
</body>
</html>
In this example, the <tbody> tag groups the rows of data in the table, making it easy to separate the body from the header.
Example 2: Table with <thead>, <tbody>, and <tfoot>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Table with Header, Body, and Footer</title>
</head>
<body>
<table border="1">
<thead>
<tr>
<th>Product</th>
<th>Price</th>
<th>Quantity</th>
</tr>
</thead>
<tbody>
<tr>
<td>Laptop</td>
<td>$800</td>
<td>2</td>
</tr>
<tr>
<td>Phone</td>
<td>$500</td>
<td>5</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>Total</td>
<td>$1300</td>
<td>7</td>
</tr>
</tfoot>
</table>
</body>
</html>
This example illustrates how the <tbody> tag works alongside the <thead> and <tfoot> tags to organize a table into clear sections.
