%! ## `inner2outer` swaps the nesting of a table whose variables are themselves
%! ## tables: the inner (nested) variables are lifted to the top level.
%!
%! Inner = table ([1; 2; 3], [4; 5; 6], 'VariableNames', {'x', 'y'})
%! NT = table ([10; 20; 30], Inner, 'VariableNames', {'id', 'inner'})
%! NT
%!
%! ## After `inner2outer` the nested `x` and `y` become ordinary variables.
%! inner2outer (NT)
