Yes they are.  Columns, themselves, can have borders, backgrounds,
widths, and a visibility; these are all taken into account when the
whole table is being assembled and painted.

And if you can select all the cells in a row and style them, I don't see why you shouldn't be also able to select all the cells in a column and style them. Conceptually it is the same, and technically it doesn't sound all that more difficult.

It is.  This isn't an arbitrary choice.  For example, which cells are
in a column is a result of styling, itself, as you can change the
'display' value for individual cells.  Further, allowing arbitrary
styling on columns to mean "style the cells in the column" means that
cells are now inheriting from *two* parents, which requires
adjudication of some sort.  It's possible that more properties could
be applied to the column itself and dealt with at the same time as
borders/etc are, but it's definitely not something you can do for
arbitrary styles.
