Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The HTMLTableElement interface provides special properties and methods (beyond the regular HTMLElement object interface it also has available to it by inheritance) for manipulating the layout and presentation of tables in an HTML document.

Instance properties

Inherits properties from its parent, HTMLElement.

HTMLTableElement.caption

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

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

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.rows Read 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.tBodies Read only

Returns a live HTMLCollection containing all the <tbody> of the element. The HTMLCollection is live and is automatically updated when the HTMLTableElement changes.

Instance methods

Inherits methods from its parent, HTMLElement.

HTMLTableElement.createTHead()

Returns an HTMLTableSectionElement representing the first <thead> 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>, nor a <colgroup>, or as the last child if there is no such element.

HTMLTableElement.deleteTHead()

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

HTMLTableElement.createTFoot()

Returns an HTMLTableSectionElement 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 as the last child.

HTMLTableElement.deleteTFoot()

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

HTMLTableElement.createTBody()

Returns a HTMLTableSectionElement representing a new <tbody> that is a child of the element. It is inserted in the tree after the last element that is a <tbody>, or as the last child if there is no such element.

HTMLTableElement.createCaption()

Returns an HTMLElement representing the first <caption> that is a child of the element. If none is found, a new one is created and inserted in the tree as the first child of the <table> element.

HTMLTableElement.deleteCaption()

Removes the first <caption> 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 is smaller than -1 or greater than the amount of rows in the collection, a DOMException with the value IndexSizeError is raised.

Examples

Using the DOM Table Interface

The HTMLTableElement interface provides some convenience methods for creating and manipulating tables. Two frequently used methods are HTMLTableElement.insertRow and HTMLTableRowElement.insertCell.

To add a row and some cells to an existing table:

html
<table id="table0">
  <tbody>
    <tr>
      <td>Row 0 Cell 0</td>
      <td>Row 0 Cell 1</td>
    </tr>
  </tbody>
</table>

js
const table = document.getElementById("table0");
const row = table.insertRow(-1);

for (let i = 0; i < 2; i++) {
  const cell = row.insertCell(-1);
  const text = `Row ${row.rowIndex} Cell ${i}`;
  cell.appendChild(document.createTextNode(text));
}
