How do I render a table of components where the size of the table is determined at runtime? #866

Pretty much the title. I am in need of an interactive table. At the moment, I'm using the grid-container component that is available outside the repository. However, it is wasting a lot of space in between the gaps. So I wanted to implement something similar to this, but cannot figure out a way to do so for a table in runtime. Here are the relevant parts of the implementation:

ftxui::Component Disp::Cell(std::string &label, const ftxui::Color &fg,
                            const ftxui::Color &hi) {
    using namespace ftxui;
    auto cell = Renderer([&](bool focused) {
        auto style = [](Element Elem) {
            return Elem | center | flex | size(WIDTH, EQUAL, 5) |
                   size(HEIGHT, EQUAL, 5);
        };
        if (focused) {
            return text(label) | bold | bgcolor(hi) | style |
                   borderStyled(BorderStyle::EMPTY);
            ;
        } else {
            return text(label) | bgcolor(Color::DarkRed) | style |
                   borderStyled(BorderStyle::EMPTY);
        }
    });
    return cell;
}

and somewhere else

    std::vector<Components> buttons(16);
    for (std::uint8_t i = 0; i < 16; i++) {
        for (std::uint8_t j = 0; j < 16; j++) {
            buttons[i].push_back(Cell(table.labels[16 * i + j],
                                      table.fgs[16 * i + j],
                                      table.his[16 * i + j]) |
                                 CatchEvents({i, j}) | center | flex);
        }
    }
