The span property of the HTMLTableColElement interface represents the number of columns this <col> or <colgroup> must span; this lets the column occupy space across multiple columns of the table. It reflects the span attribute.

Note: When setting a new value, the value is clamped to the nearest strictly positive number (up to 1000).
