Page layout - mimic html cell span

hi there, I’m slowly migrating from OH2.5 to 3.1
I’m recreating a Ui using the new pages objects.
In sitemaps I was used to work like in html table layouts, now I’m not able -using responsive layout- to recreate the cellspan or rowspan layout.

i would like to have a cell block on the left as high as 2 cell blocks on the right.
is there a way? thanks for your help
