2. Set column description to numbers.
3. run DataTable data = CsvDataSourceHelper.read(reader, columnDescriptions, 
false);
4. serve and parse in client

What is the expected output? What do you see instead?
The numbers should be parsed as scientific notation, but it looks like it 
ignores anything after E.
