Answer 1

Yes, it should be fairly straightforward to do this.

Start by adding in the name in the right location int he colModel, then in your jqGrid setup you can inject a blank column via:

        beforeProcessing: function (data, status, xhr) {
            //add a "blank" column that will be built
            for (var x = 0, length = data.rows.length; x < length; x++) {
                data.rows[x].cell.splice(ColumnIndexValueToAddBlank,0, "");
            }//for
        }, //beforeProcessing

then in that column setup in the jqGrid (in the right location in the colModel setup)

        { name: "CalculatedColumn", .... , formatter: CalculatedFormatFunction

The custom formatter function:

  function CalculatedFormatFunction(cellval, opts, rowObject, action) {

   return rowObject[ColumnOneIndex] * rowObject[ColumnTwoIndex]; 
  }
