Show column types in headers

[arina-ielchiieva]

SqlLine has ability to show headers which include column names. It could be useful to add functionality to show column types which can be turned on / off. Default off.

Can you give an example of how the output would look?

[arina-ielchiieva]

For example, for table output format type can be added right underneath the column name:

+---------+
|      C1      |
| INTEGER |
+---------+
| 1             |
+---------+

Formatting would be better, github just shows this way.

OK, sounds good. There are properties showheader, showwarnings, showelapsedttime already, so maybe this could be showtypes.
