dynamically resize width of tables next to each other?

Hi,

In optimized design experience on a canvas page with canvas size dynamic there are two tables next to each other and users can add/change no. of dimensions per NavigationPanel.
At the moment both tables are set to 50% width which is not optimal if e.g. left table only has one dimension and right table 3 dimensions. It would be nice if in this case the left table resizes its width (< 50%) and right table can expand its width if needed and vice versa.
is this in any way achievable?
