The createTHead()
method of HTMLTableElement
objects returns the <thead>
element associated with a given <table>
. If no header exists in the table, this method creates it, and then returns it.
Note: If no header exists, createTHead()
inserts a new header directly into the table. The header does not need to be added separately as would be the case if Document.createElement()
had been used to create the new <thead>
element.
