How come the closure for addColumns does NOT pass the row index?

[thedangler]

Wondering why when trying to manage columns you can't access the index of the record you are looping?

For example if doing a custom field
->addColumn('myCustomField', function($col){
// how do I get the current iteration of row?
});

// this would be nice. Unless there is a way to do it I can't find in the docs
->addColumn('myCustomField', function($col, $index){
// how do I get the current iteration of row?
});

Please not this is for a Collection.

you can make a private variable say it "index" with default value is 1. on your return closure function $this->index++;
