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