Properties

Inherits properties from its parent, HTMLElement.

HTMLTableElement.caption

Is a HTMLTableCaptionElement representing the first <caption> that is a child of the element, or null if none is found. When set, if the object doesn't represent a <caption>, a DOMException with the HierarchyRequestError name is thrown. If a correct object is given, it is inserted in the tree as the first child of this element and the first <caption> that is a child of this element is removed from the tree, if any.

HTMLTableElement.tHead

Is a HTMLTableSectionElement representing the first <thead> that is a child of the element, or null if none is found. When set, if the object doesn't represent a <thead>, a DOMException with the HierarchyRequestError name is thrown. If a correct object is given, it is inserted in the tree immediately before the first element that is neither a <caption>, nor a <colgroup>, or as the last child if there is no such element, and the first <thead> that is a child of this element is removed from the tree, if any.

HTMLTableElement.tFoot

Is a HTMLTableSectionElement representing the first <tfoot> that is a child of the element, or null if none is found. When set, if the object doesn't represent a <tfoot>, a DOMException with the HierarchyRequestError name is thrown. If a correct object is given, it is inserted in the tree immediately before the first element that is neither a <caption>, a <colgroup>, nor a <thead>, or as the last child if there is no such element, and the first <tfoot> that is a child of this element is removed from the tree, if any.

HTMLTableElement.rowsRead only

Returns a live HTMLCollection containing all the rows of the element, that is all <tr> that are a child of the element, or a child of one of its <thead>, <tbody> and <tfoot> children. The rows members of a <thead> appear first, in tree order, and those members of a <tbody> last, also in tree order. The HTMLCollection is live and is automatically updated when the HTMLTableElement changes.

HTMLTableElement.tBodiesRead only

HTMLTableElement.deleteTHead()

Removes the first <thead> that is a child of the element.

HTMLTableElement.createTFoot()

Returns an HTMLElement representing the first <tfoot> that is a child of the element. If none is found, a new one is created and inserted in the tree immediately before the first element that is neither a <caption>, a <colgroup>, nor a <thead>, or as the last child if there is no such element.

HTMLTableElement.deleteTFoot()

Removes the first <tfoot> that is a child of the element.

HTMLTableElement.insertRow()

Returns an HTMLTableRowElement representing a new row of the table. It inserts it in the rows collection immediately before the <tr> element at the given index position. If necessary a <tbody> is created. If the index is -1, the new row is appended to the collection. If the index is smaller than -1 or greater than the number of rows in the collection, a DOMException with the value IndexSizeError is raised.

HTMLTableElement.deleteRow()

Removes the row corresponding to the index given in parameter. If the index value is -1 the last row is removed; if it smaller than -1 or greater than the amount of rows in the collection, a DOMException with the value IndexSizeError is raised.
