Also:

1. Add a "units" column to the right of existing. just to get more width, to make the horizontal scrollbar operation more interesting when :max-table-width is being scrolled by user (see suggestion above in screenshot).
2. When :max-rows is turned off (via a tickbox) the table will expand vertically as far as it can. So you might need to set container height. Maybe. Put some text in explaining this. Ie. when the tickbox is ticked, show the slider, and when it is not ticked show text explaining how the size is now constrained by the container and will expand as much as possible.

Add more padding between the elements (and more vertical spacing?)

Also, add :align-center to those h-boxes to improve their positioning
