# Interface HTMLTableElement

All Superinterfaces:
  `Element, HTMLElement, Node`

public interface HTMLTableElement extends HTMLElement
The create* and delete* methods on the table allow authors to construct and modify tables. HTML 4.0 specifies that only one of each of the `CAPTION` , `THEAD` , and `TFOOT` elements may exist in a table. Therefore, if one exists, and the createTHead() or createTFoot() method is called, the method returns the existing THead or TFoot element. See the TABLE element definition in HTML 4.0.

See also the Document Object Model (DOM) Level 2 Specification.

Since:
  1.4, DOM Level 2
