note: the colors are ok - they work on dark and bright terminal background colors

> It should be possible to make it more immediately obvious what the structure of your
CQL table is from cqlsh. Two minor enhancements could go a long way:
> 1) If there are no results display the column headers anyway. Right now, if you are trying
to do a query and get no results, it's common to need to display the table schema to figure
out what you did wrong. Having the columns displayed whenever you do a query wouldn't get
in the way, and would provide a more visual way than by describing the table.
> 2) Along with the first one, if we could highlight the partition/clustering columns in
different colors, it would be much more intuitively 
> understandable what the underlying partition structure is.
> tl;dr: the forms below should each have distinct visual representation when displaying
the column headers, and the column headers should always be shown.
> CREATE TABLE usertest (
>   userid text,
>   email text,
>   name text,
>   PRIMARY KEY (userid)
> ) 
> CREATE TABLE usertest2 (
>   userid text,
>   email text,
>   name text,
>   PRIMARY KEY (userid, email)
> )
> CREATE TABLE usertest3 (
>   userid text,
>   email text,
>   name text,
>   PRIMARY KEY ((userid, email))
> )
