<tfoot>
HTML <tfoot> Tag
The <tfoot> tag defines the footer of an HTML table. It is used together with the <thead> and <tbody> elements, which define the header and the body of the table correspondingly.
The <tfoot> tag must be declared inside the <table> element, after the <caption>, <colgroup> (if any) and the <thead> elements. Note, that <tfoot> must be placed before <tbody>, so that the browser can render the table footer correctly.
The <tfoot> tag must contain at least one <tr> tag.
The <thead>, <tbody>, and <tfoot> elements do not affect the layout of the table by default. Use CSS properties to customize the look of the table.

The <tfoot> and other tags for summarizing table contents
The <tfoot> element provides summary information about the content of an HTML table. It comes either before or after the tbody element of the table, but is always rendered at the bottom of the table.
Use the <tfoot>, <tbody>, and <thead> elements to arrange tables containing complex data sets. Due to these elements users can scroll the contents of the table independently of the header and footer.
