Table panel: layout and responsive design: ok below 768px

I am building a dashboard and want to ensure it is responsive.
I have 3 tables (simple) side to side.
When my display is big enough (wide PC), no problem
When the display is little (<768px), the tables automatically stacks on each others.
My problem is in between (see attached picture). The table size down and we are not able to view all collums. I would like to tall grafana to stack the 3 table “before”, example: 1200px or more.

Is-it something possible or does anyone has a workaround?

Thanks !
