I've added another parameter in the config for the search-method. You can now specify fieldName separately from the formula. I actually documented it, but forgot to implement it in the demo.
This should make it easier to refer to fields in the columns.
formula: 'LastName + ", " + FirstName',
If you want to have a demo of something more in regards search-results/data tables, leave a comment, and I'll take a look at it. If it's something I can do in a relatively short amount of time, I'll make/post a demoapp with a simple description.
