Good question. We have implemented "sub-modes" (i.e. mode within another mode) 
in a few places, but there has been some pushback from folks who think that it 
makes it more difficult to discover functionality. Furthermore, rename_column 
was added in 1.8.0 so moving it into a sub-mode would represent a compatibility 
break in the CLI. Probably not a major one, but an inconvenient one nonetheless.

So I think I'd vote for keeping all of the column actions rooted in the 'table' 
mode. But I'm open to changing it if others feel strongly about adding a 
'column' sub-mode.
