                if (lboxColor.val() != null) {

For those struggling to get data from only one column AND only from visible rows: you can actually combine the "selectors" like this

var total = api
      .column(2, { search: 'applied' }) // <-- only 3rd column && only visible after applied search
      .data()
      .reduce(function (a, b) {
        return floatVal(a) + floatVal(b)
      }, 0)

I also notices several sources stating { page: 'current' } would be the right selector for currently visible rows, but this one actually gives you the rows visible after a possible pagination.
