Eclipse Indigo is more than 5 years old. NatTable 1.5 is quite new. I suppose the signatures doesn't match with that difference.

I suggest to update the IDE to a more current version like Oxygen and use a Target Definition if you need to stick with Indigo as the base of your application. From my point of view there is no reason to stick with such an old version of an IDE.
