HTMLTableElement: createTHead() method
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.
Syntax
js
createTHead()
Parameters
None.
Return value
HTMLTableSectionElement
Examples
js
let myHead = myTable.createTHead();
// Now this should be true: myHead === myTable.tHead
