Hi! I try to use etableand do not understand what is correct format to use function formatter in it. If I write

> "formatter":function(x) {return x?'Used':'Unused'}

it is JSON syntax error. If I add quotes, like here:

> "formatter":"function(x) {return x?'Used':'Unused'}"

it does not work in etable. It looks like it is Tabulator syntax error 🙂  
How to do that in correct manner?  
Of course my real formatter is more complex.
