ischnaged method for valur attribute

Hello Gurus,

I have a scenario where I want to know if the value of any table cell got changed at runtime

Say there is a node Node1-->Attribute1

                                         -->Attribute 2

I did some research and found the method wdContext.nodeNode1.getNode1ElementAt(i).ischanged.

I am looking for a method which can check if wdContext.nodeNode1.getNode1ElementAt(i).getAttribute1()  got changed.

Thanks,
