Code review comment for ~mpontillo/maas:default-domain-ui--bug-1756745

Thanks for the help and feedback.

I've moved forward using the col-N classes, since I see regressions with regard to column alignment (and sometimes placement of the confirm message) in this table every time I try to use the new CSS-based method.

I've also hard-coded a min-height style for now, to make all the rows the same height (regardless of whether or not they have an actions menu)
