Try SET Verbatim = 1 in the script before loading the data. I'm not sure that will help. I don't think chr(10) and chr(13) are stripped out when loading the data. So it could be something else. Perhaps the table object ignores them.
Looking into it further this appears to be the case. The table is showing the line returns removed but when you hover over the field the line returns are there. I don't see a setting in the table viz to remove line breaks so is there some other way around this behavior?
