# tr insertCell() Method

tr Object

## Definition and Usage

The insertCell() method inserts a cell into the current row.

## Syntax

trObject.insertCell(index)

Value | Description
--- | ---

index

An integer (starts at 0) that specifies the position of the new cell in the current row. The value of -1 can also be used; which results in that the new cell will be inserted at the last position.
If this parameter is omitted, insertCell() inserts the new cell at the last position in IE and at the first position in Chrome and Safari.
This parameter is required in Firefox and Opera, but optional in Internet Explorer, Chrome and Safari.

## Browser Support

The insertCell() method is supported in all major browsers.

## Example

Insert new cell(s) in the first table row:

<html>
<head>
<script>
function displayResult()
{
var firstRow=document.getElementById("myTable").rows[0];
var x=firstRow.insertCell(-1);
x.innerHTML="New cell"
}
</script>
</head>
<body>
<table id="myTable" border="1">
<tr>
<td>First cell</td>
<td>Second cell</td>
<td>Third cell</td>
</tr>
</table>
<br>
<button type="button" onclick="displayResult()">Insert cell</button>
</body>
</html>
