The <tr> HTML element is used to define a row in a table. It stands for "table row" and serves as a container for <th> (table header) and <td> (table data) elements, which represent the individual cells within the row. The <tr> element is a fundamental part of HTML tables, organizing the data into horizontal rows.
Usage and Characteristics
The <tr> element is used within a <table>, <thead>, <tbody>, or <tfoot> element to group cells into a single row. Each <tr> contains one or more <th> or <td> elements, depending on whether the row is part of the table's header or body. Here is an example of how the <tr> tag can be used:
<table>
<thead>
<tr>
<th>Item</th>
<th>Quantity</th>
<th>Price</th>
</tr>
</thead>
<tbody>
<tr>
<td>Apples</td>
<td>10</td>
<td>$1.00</td>
</tr>
<tr>
<td>Bananas</td>
<td>5</td>
<td>$0.50</td>
</tr>
</tbody>
