Hello

You also can use calculated fields.

Create Calculated field CalcField

Code:
procedure TForm1.MemTableEh1CalcFields(DataSet: TDataSet);
begin
  MemTableEh1.FieldByName('CalcField').AsBCD :=
    MemTableEh1.FieldByName('Population').AsFloat /
    MemTableEh1.FieldByName('Area').AsFloat;
end;


and adjust its summation in the footer of the column.

Code:
      item
        CellButtons = <>
        DynProps = <>
        EditButtons = <>
        FieldName = 'Population'
        Footer.FieldName = 'CalcField'
        Footer.ValueType = fvtSum
        Footers = <>
      end
