main.cpp:

type expected = {
    { 
        "1",
        {
            {"1",  1, 2},
            {"1", 11, 6}
        }
    },
    {
        "13",
        {
            {"13",  13, 0},
            {"13", 132, 3},
            {"13", 133, 5}
        }
    },
    {
        "14",
        {
            {"14", 14, 1}
        }
    },
    {
        "15",
        {
            {"15", 15, 4}
        }
    }
};

result after formatting

type expected = {
    { "1",                                                                                  {{"1", 1, 2}, {"1", 11, 6}}},
    {"13", {{"13", 13, 0}, {"13", 132, 3}, {"13", 133, 5}}},
    {"14",                                                                                                                  {{"14", 14, 1}}},
    {"15",                                                                                                                  {{"15", 15, 4}}}
};

The formatted result makes no sense.

proposal

Proposal is to format nested array of structures as in input file above. I.e. if an array has another array as one of it's elements, then this array is formatted as one element per line.

Another perhaps more general case, is that a two+ dimensional array of standard type variables, such as int or float, doesn't follow the alignment setting.
