Issue with IDs of zero

[sconstantinides]

Thanks for the awesome plugin.

When using a numerical ID, values of 0 are returned as undefined. For example, if the result array should be [0, 10, 20] it is returned as [undefined, 10, 20].

I think I know what's causing this and could do a pull request to fix it, but just to clarify: you're setting the id option to 0?

I don't think so... I'm setting the id option to a string, in this case 'Row number'. The problem is that when 'Row number' is 0, the result array doesn't include it.
