41 ///
42 /// This is provided for test simplicity's sake.  Having to match the result of
43 /// the formatting on a line by line basis would result in too verbose tests
44 /// (maybe not with C++11, but not using this yet).
45 ///
46 /// Because of the flattening of the formatted table into a string, we risk
47 /// misdetecting problems when the algorithm bundles newlines into the lines of
48 /// a table.  This should not happen, and not accounting for this little detail
49 /// makes testing so much easier.
50 ///

52 ///     lines separated by newline characters.
53 /// \param formatter The formatter to use.
