HTML <thead> Tag
The <thead> tag defines the header of an HTML table. The tag is used along with <tbody> and <tfoot> tags, that specify the body and footer of the table, respectively.
The <thead> tag must be used as a child of the <table> element, after the <caption>, <colgroup> elements and before the <tfoot>, <tbody>, and <tr> elements. (You can use only one <thead> tag inside <table>).
Note that the <tfoot> tag must be placed before <tbody>, so that the browser can render the table footer correctly.
DANGER
The <thead> must contain at least one <tr> element.
TIP
The <thead>, <tbody>, and <tfoot> elements do not affect the table layout by default. Use CSS properties to customize the look of the table.
Syntax
The <thead> tag comes in pairs. The content is written between the opening (<thead>) and closing (</thead>) tags.
