/**

    The insertCell() method inserts an empty TD cell into this row. 
    If index is -1 or equal to the number of cells, the new cell is
    appended.

    
    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 last TD element.  Invoke the
    insertCell() with an index of negative one
    which will append the empty cell to the end of the list.
    Check the value of the newly created cell and make sure it is null
    and also the numbers of cells should now be seven.
