This causes the xcolor package to load and integrate with the colortbl package, for coloring rows / columns of tabular tables.
Otherwise, to get proper integration, the user has to call \PassOptionsToPackage{table}{xcolor} before \documentclass{sp}, which isn't terribly intuitive.
The colortbl package adds several commands that many users won't use, but they don't conflict with anything else, as far as I know, so no harm done.
