If the field width of each column is not fixed and you don't know the max length of each field, then you'll probably need to read-in the full data into an array (maybe a 2d array) and then calculate each field width. I have not done any testing, but my first thought would be to use the Array::Transpose and List::Util modules in this calculation process.
