The insertCell() method inserts an empty TD cell into this row. Retrieve the fourth TR element and examine the value of the cells length attribute which should be set to six. Check the value of the first TD element. Invoke the insertCell() which will create an empty TD cell at the zero index position. Check the value of the newly created cell and make sure it is null and also the numbers of cells should now be seven.
