One of the nodes I use puts the log for a calculation it does as an entry in the data table. The log is simple unformatted fixed-width text, and can be 500 lines long. There is currently no sensible way to view this in KNIME - the data table view lets you view the first hundred lines or so at best, but you are limited by having to manually resize the column height. The document viewer nodes assume HTML input and so word-wrap the text, which makes it illegible.
Am I missing something?
