  * You can continue formatting the [FormattedFrame] by calling [format][FormattedFrame.format] on it again.

  * Formatting is done additively, meaning you can add more formatting to a cell that's already formatted or
  * override certain attributes inherited from its outer group.
  *
+ * Specifying a [frame column][FrameColumn] at the moment does nothing
