This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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.
createTHead()
None.
HTMLTableSectionElement let myHead = myTable.createTHead(); // Now this should be true: myHead === myTable.tHead
