# We've seen how to apply styles to a selection of cells by setting the
# individual properties. Another option is to use the <code>style</code> method
#
# <code>style</code> lets us define multiple properties at once with a hash. It
# also accepts a block that will be called for each cell and can be used for
# some complex styling.
