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 read-only 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.

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.
