The <tfoot> tag is used to >group footer content in an HTML table. The <foot> element is used in conjunction with the <thead> and <tbody> elements to specify each part of a table (footer, header, body).Browsers can use these elements to enable scrolling of the table body independently of the header and footer. Also, when printing a large table that spans multiple pages, these elements can enable the table header and footer to be printed at the top and bottom of each page.
The <tfoot> element must have one or more "tr" tags inside. It must be used as a child of a "table" element, after any "caption", "colgroup", "thead", and "tbody" elements. The "thead", "tbody", and "tfoot" elements will not affect the layout of the table by default. However, you can use CSS to style these elements!
