If you want multiple column sorting:

function grid_sorter(args, grid, dataView) {
    let cols = args.sortCols;
    console.log(cols)
    dataView.sort(function (dataRow1, dataRow2) {
        for (let i = 0, l = cols.length; i < l; i++) {
            let field = cols[i].sortCol.field;
            let sign = cols[i].sortAsc ? 1 : -1;
            let value1 = dataRow1[field], value2 = dataRow2[field];
            let result = (value1 === value2 ? 0 : (value1 > value2 ? 1 : -1)) * sign;
            if (result !== 0) {
                return result;
            }
        }
        return 0;
    });
    grid.invalidate();
    grid.render();
}

grid_sorter(default_sorting, grid_2, dataView_2);

cols is an object like this:

- sortCols {
  - length: 2
  - 0 : {
       "sortAsc: true,
       "sortCol": {
           "field: column_id
        }
      }
  - 1: {..}
}
