HTMLTableCellElement: rowSpan property

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 rowSpan property of the HTMLTableCellElement interface represents the number of rows this cell must span; this lets the cell occupy space across multiple rows of the table. It reflects the rowspan attribute.

In this article

Value

A positive number representing the number of rows. If it is 0, it means all remaining rows in the column.

Note: When setting a new value, a value different from 0 is clamped to the nearest strictly positive number.

Examples

This example provides two buttons to modify the row span of the first cell of the body.

HTML

html
<table> <thead> <tr> <th>Col 1</th> <th>Col 2</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>1</td> </tr> <tr> <td rowspan="2">2</td> <td>2</td> </tr> <tr> <td>3</td> <td>3</td> </tr> <tr> <td>4</td> <td>4</td> </tr> </tbody> </table> <button id="increase">Increase rowspan</button> <button id="decrease">Decrease rowspan</button> <div>The second cell of the first column spans <output>2</output> row(s).</div>
table { border-collapse: collapse; } th, td, table { border: 1px solid black; } button { margin: 1em 1em 1em 0; }
