This is a good article for how to use a compenent that is very badly documented in Books Online and everywhere else. I used the Script Component transformation to "condense" a table that i could see was possible any other way. It took a lot of searching to find how to overwrite the appropriate subroutines and output to a new buffer, whch could subsequently be put into a table. I think that when there is a lack of documentation in this way people just don't use the component as they don't really know what it is for, which is a shame as it has its uses.
