  <p>Contents: Comma-delimited list of CSS style classes that will be applied
  to the rows of this table.  A space separated list of classes
  may also be specified for any individual row.  Thes styles are
  applied, in turn, to each row in the table.  For example, if
  the list has two elements, the first style class in the list
  is applied to the first row, the second to the second row, the
  first to the third row, the second to the fourth row, etc.  In
  other words, we keep iterating through the list until we reach
  the end, and then we start at the beginning again.
