    It is possible to insert a custom row at the bottom of the grid with
    %code last_row
    and a custom row before or after a certain row with
    %code before_row
    and
    %code after_row.
  %p
    The block of
    %code before_row
    or
    %code after_row
    is executed for each record and if it returns a string.
  %p
    Both
    %code before_row
    and
    %code last_row
    are expected to return the complete markup for a table row starting with the
    %code tr
    tag.
  %p
    The first argument for a
    %code last_row
    block and the second argument for
    %code before_row
    and
    %code after_row
    blocks is the number of columns in the grid.
