– Table Body Section
<tfoot> are HTML elements that structure tables into header, body, and footer sections for better organization and semantics. 1. <thead> contains column headers using elements and appears once per table, improving accessibility and styling; 2.
<tbody> holds the main data rows with elements and is often added automatically by browsers if omitted; 3.
<tfoot> defines summary or total rows, must be placed after <thead> but before
<tbody> in HTML, yet renders visually at the table’s bottom, supports repeated footers in print, and enhances usability for large tables. These elements improve accessibility, enable targeted CSS styling, aid JavaScript manipulation, and help maintain clarity in complex tables, making them a best practice in HTML table design.
The <thead>, <code><tbody>, and <code><tfoot> are HTML elements used to divide a table into logical sections: the <strong>header</strong>, <strong>body</strong>, and <strong>footer</strong>. They help structure tables in a more organized and semantically meaningful way—especially useful for accessibility, styling with CSS, and scripting with JavaScript.<img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175381304633448.jpeg" class="lazy" alt="What are <thead>, <tbody>, and <tfoot> in tables?">, </tfoot>

<li>Wraps the <strong>header rows</strong> of the table (usually the column titles).</li>
<li>Should contain one or more <code><tr> elements with <code><th> (header cells).<li>Appears <strong>once</strong> per table, and must be a direct child of <code><table>.<li>Even if you don’t use it, browsers often add it automatically in the DOM.</li>

- Contains the main data rows of the table.
- This is where most of your
<tr> rows go. - If you don’t include
<tbody> in your HTML, browsers usually insert it automatically.
Example:
<tbody>
<tr>
<td>John</td>
<td>28</td>
<td>New York</td>
</tr>
<tr>
<td>Sara</td>
<td>32</td>
<td>Los Angeles</td>
</tr>
</tbody>
<tfoot> – Table Footer Section
- Used for summary or totals rows (e.g., sums, averages).
- Should come after
<thead> but before <tbody> in the HTML (yes, really!). - Despite being defined early in the code, it renders at the bottom of the table.
- Also useful for repeating footers when printing long tables.
Example:
, <tbody>, and <tfoot> in tables?" /><tfoot>
<tr>
<td>Total:</td>
<td>60</td>
<td></td>
</tr>
</tfoot>
Why Use These Sections?
- Accessibility: Screen readers can better interpret table structure.
- Styling: You can style header, body, and footer differently:
thead th {
background-color: #003366;
color: white;
}
tfoot td {
font-weight: bold;
} - Long Tables: Browsers can keep the header/footer visible when scrolling.
- Printing: Footers can repeat on each printed page.
Full Example:
<table>
<thead>
<tr>
<th>Product</th>
<th>Price</th>
<th>Stock</th>
</tr>
</thead>
<tfoot>
<tr>
<td>Total</td>
<td>$150</td>
<td>45</td>
</tr>
</tfoot>
<tbody>
<tr>
<td>Laptop</td>
<td>$100</td>
<td>20</td>
</tr>
<tr>
<td>Mouse</td>
<td>$50</td>
<td>25</td>
</tr>
</tbody>
</table>Note: Even though <tfoot> appears before <tbody> in the code, it will display at the bottom of the table.
So, in short:
<thead> = header rows (column titles)<tbody> = main data rows<tfoot> = footer/summary rowsUsing them makes your tables cleaner, more maintainable, and more usable—especially for complex or large datasets. Basically, it's a best practice for well-structured HTML tables.
