The HTMLTableSectionElement interface provides special properties and methods (beyond the HTMLElement interface it also has available to it by inheritance) for manipulating the layout and presentation of sections, that is headers, footers and bodies (<thead>, <tfoot>, and <tbody>, respectively) in an HTML table.

Inherits properties from its parent, HTMLElement.

HTMLTableSectionElement.align Deprecated

A string containing an enumerated value reflecting the align attribute. It indicates the alignment of the element's contents with respect to the surrounding context. The possible values are "left", "right", and "center".

HTMLTableSectionElement.rows Read only

Returns a live HTMLCollection containing the rows in the section. The HTMLCollection is live and is automatically updated when rows are added or removed.

HTMLTableSectionElement.ch Deprecated

A string containing one single character. This character is the one to align all the cell of a column on. It reflects the char and default to the decimal points associated with the language, e.g. '.' for English, or ',' for French. This property was optional and was not very well supported.

HTMLTableSectionElement.chOff Deprecated

A string containing an integer indicating how many characters must be left at the right (for left-to-right scripts; or at the left for right-to-left scripts) of the character defined by HTMLTableRowElement.ch. This property was optional and was not very well supported.

HTMLTableSectionElement.vAlign Deprecated

A string representing an enumerated value indicating how the content of the cell must be vertically aligned. It reflects the valign attribute and can have one of the following values: "top", "middle", "bottom", or "baseline".

Inherits methods from its parent, HTMLElement.

HTMLTableSectionElement.deleteRow()

Removes the row, corresponding to the index given in parameter, in the section. 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.

HTMLTableSectionElement.insertRow()

Returns an HTMLTableRowElement representing a new row of the section. It inserts it in the rows collection immediately before the <tr> element at the given index position. 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.
