Hi @dimendia,

Setting the columns like that is a feature that exists in the Premium Extension of our plugin, thanks to the Customizer it adds. You get more control over the layout thanks to drag & drop action.
Otherwise it is quite the endeavor which would involve creating your own custom template. This guide will have more information for you regarding the process & knowledge of HTML & CSS, especially regarding tables will also go a long way:
