As others mentioned in order to use self executing function with parameters you need to provide those parameters.

let myCol; // or you can set this to an initial value
let myRow;

data.forEach(function (col, row) {
            return function (o) {
                // your logic here
            };
        }(myCol, myRow));

Your typescript compiler is complaining because your function takes two parameters col and row but you are invoking it without any parameter.
