Although the property itself is read-only, the returned object is live and allows the modification of its content.
HTMLCollectionObject = table.rows;
HTMLCollection providing a live-updating list of the
HTMLTableRowElement objects representing all of the
<tr> elements contained in the table. This provides quick access to all of the table rows, without having to manually search for them.
myrows = mytable.rows; firstRow = mytable.rows; lastRow = mytable.rows.item(mytable.rows.length-1);
This demonstrates how you can use both array syntax (line 2) and the
HTMLCollection.item() method (line 3) to obtain individual rows in the table.
