Definition and Usage
The createTHead() method creates an empty <thead> element and adds it to the table.
Note: If a <thead> element already exists on the table, the createTHead() method returns the existing one, and does not create a new one.
Note: The <thead> element must have one or more <tr> tags inside.
Tip: To remove the <thead> element from a table, use the deleteTHead() method.
