Of the parent table's child elements, <tbody> represents the content which, when longer than a page, will most likely differ for each page printed; while the content of <thead> and <tfoot> will be the same or similar for each page printed. For displays, <tbody> will enable separate scrolling of the <thead>, <tfoot>, and <caption> elements of the same parent <table> element. Note that unlike the <thead>, <tfoot>, and <caption> elements however, multiple <tbody> elements are permitted (if consecutive), allowing the data-rows in long tables to be divided into different sections, each separately formatted as needed.<td>) defines a cell of a table that contains data.
