The HTML <caption> Element (or HTML Table Caption Element) represents the title of a table. Though it is always the first descendant of a <table>, its styling, using CSS, may place it elsewhere, relative to the table.
The HTML Table Body Element (<tbody>) defines one or more <tr> element data-rows to be the body of its parent <table> element (as long as no <tr> elements are immediate children of that table element.) In conjunction with a preceding <thead> and/or <tfoot> element, <tbody> provides additional semantic information for devices such as printers and displays. 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.
The onchange event handler of the DataStore interface fires when a change is made to the data store. Its main use is to synchronize different apps that are using the data store when a change is made. When fired, this event returns a DataStoreChangeEvent, which can be used to handle the change that was just made. Alternatively, when the event fires you could create a DataStoreCursor and iterate through all the records, if needed.
