                                                , dataSrc: [1]

I want to calculate running totals or say some calculations based on grouped rows . i.e first row of the current group and last row of the current group.. how to do it?

    This example sums everything in the group. You can just get the first and last rows like this:

                    var salaryAvg = rows
                        .data()
                        .pluck(5)
    
    var first = salaryAvg[0];
    var last = salaryAvg[salaryAvg.length - 1];
