Tag <thead> Uses
To arrange header information in HTML tables, use the Tag Thead <thead>.
To indicate a table’s head (body and footer), add the Tag <thead> with the Tag <tbody> and Tag <tfoot> elements.
By using these elements, browsers can navigate the table body on their own from the header and footer. Furthermore, if a large table occupies multiple pages, the table header and footer can be displayed at the beginning and end of each.
The Tag <thead> should be positioned accordingly: under a <table> element, followed by <caption>, <colgroup> elements prior to <tbody> , <tfoot> and <tr>.
Common Uses
Here are some common uses of the <thead> tag:
- The <thead> tag is used to define the headers of a table. The header cells provide a brief description of the data that is contained in each column.
- The <thead> tag is often used in conjunction with JavaScript libraries to provide dynamic sorting of table data. When a user clicks on a header cell, the JavaScript code can sort the data based on the contents of that column.
- By using the <thead> tag to define the headers of a table, developers can improve the accessibility of the table for users who rely on assistive technologies such as screen readers. The header cells are announced separately from the data cells, making it easier for users to understand the structure of the table.
- The <thead> tag can be used to create a more structured and organized table. By visually separating the header cells from the rest of the table, developers can make it easier for users to understand the relationships between the data.
- The <thead> tag can be styled using CSS to change the appearance of the table headers. This can help to make the table more visually appealing and easier to read.

}Tag <thead> Benefits
The <thead> tag in HTML provides several benefits, including:
- By using the <thead> tag to define the header section of a table, developers can create more structured and organized tables. The header cells are visually separated from the rest of the table, making it easier for users to understand the relationships between the data.
- The <thead> tag can improve the accessibility of tables for users who rely on assistive technologies such as screen readers. By identifying the header cells using the <th> tag within the <thead> section, screen readers can announce the headers separately from the data cells, making it easier for users to understand the structure of the table.
- Tables can be divided into different sections using the <thead>, <tbody>, and <tfoot> tags. This allows developers to provide additional information or structure to the table without cluttering the main data cells. For example, the <tfoot> tag can be used to display summary information such as totals or averages.
- The <thead> tag can be styled using CSS to change the appearance of the table headers. For example, developers can change the font size, color, or background color of the headers to make them stand out more.
