The HTMLTableRowElement.insertCell()
method inserts a new cell (<td>
) into a table row (<tr>
) and returns a reference to the cell.
Note: insertCell()
inserts the cell directly into the row. The cell does not need to be appended separately with Node.appendChild()
as would be the case if Document.createElement()
had been used to create the new <td>
element.
You can not use insertCell()
to create a new <th>
element though.
Syntax
var newCell = HTMLTableRowElement.insertCell(index);
HTMLTableRowElement
is a reference to an HTML <tr>
element.
Parameters
index
Optionalindex
is the cell index of the new cell. Ifindex
is-1
or equal to the number of cells, the cell is appended as the last cell in the row. Ifindex
is greater than the number of cells, anIndexSizeError
exception will result. Ifindex
is omitted it defaults to-1
.
Return value
newCell
is an HTMLTableCellElement
that references the new cell.
Example
This example uses HTMLTableElement.insertRow()
to append a new row to a table.
We then use insertCell(0)
to insert a new cell in the new row. (To be valid HTML, a <tr>
must have at least one <td>
element.) Finally, we add some text to the cell using Document.createTextNode()
and Node.appendChild()
.
HTML
<table id="my-table"> <tr><td>Row 1</td></tr> <tr><td>Row 2</td></tr> <tr><td>Row 3</td></tr> </table>
JavaScript
function addRow(tableID) { // Get a reference to the table let tableRef = document.getElementById(tableID); // Insert a row at the end of the table let newRow = tableRef.insertRow(-1); // Insert a cell in the row at index 0 let newCell = newRow.insertCell(0); // Append a text node to the cell let newText = document.createTextNode('New bottom row'); newCell.appendChild(newText); } // Call addRow() with the table's ID addRow('my-table');
