Vertical text alignment for tables

I notice that when I use tables (columns) the text appears to be 'justified' by default - with no adjustment to align top or bottom. Often I do not have an equal number to entries in each column, and so the column entries are not uniform horizontally (in alignment) across the columns. While I understand unequal entries will by definition not be equal to each other, it's be nice to have all of the text/entries in alignment with each other, with the difference(s) showing only at the bottom.

Thanks
