Where are we using this ?
@end_time = Time.now
{quote}
This is to determine the time taken for the command to execute, the
{{start_time}} variable is initialized before the call to this function.
Added a new patch with proper formatting now. Please suggest if there are
better ways to format it. This formatting may be little disrupted if table
names are huge or viewing screen size is small, when a single row of data
extends up to 2 or more lines.
The {{formatter.rb}} file doesn't help format if there are more than 2 columns
to be displayed.

Here's one mechanism to get the regions for a particular table from the shell -
it would be relatively easy to turn it into a command. It's a little hackish as
it reads an internal variable of the shell admin instance but when integrated
as a command, it could use an appropriate mechanism...
