Nested rows/column

[LukaszFormela]

Hello, I'm struggling to make the design that looks as follows. I need to put one row ("Primary Information") directly above another ("Materials"), otherwise there's a lot of unused blank space as "Materials" is pushed to new line, just below "Additional Information".
Would it be possible to achieve it?

You can achieve the result like in the picture like this:

public function layout(): array
{
    return [
        Layout::columns([
            [
                PrimaryInformationRow::class,
                MaterialsRow::class,
            ],
            AdditationalInformation::class,
        ]);
}

Wow, wish I knew that earlier :) What a great piece of software, hats off!
