This method overloads the store method inherited from the ContainerNode
 class to forbid addition of further nodes.

 ==== Parameters
 node::  A reference to the node to be added.
def store(node)
   RTFError.fire("Table row nodes cannot have nodes added to.")
end
 This method generates the RTF document text for a TableCellNode object.
