Good, I see you're making progress!

One thing I noticed on quick glancing is that you are overusing string
interpolation.

self =~ "#{s}" -> self =~ s.to_s

if "#{ val }".empty? -> if val.to_s.empty?

In []= you are evaluating the same condition twice.

I also share Andrew's feeling that you might get away with less code.
Somehow it feels like you put too much into the class.  For example,
methods #strip! and #upcase! deal with individual cell manipulations.
They may make sense as convenience methods but would first try to
focus on the core functionality of the spreadsheet: inserting and
removing rows and columns. And method #test does not belong there this
should go into a test class.

Another thing that stroke me odd is that you assume there will always
be one header row.  IMHO that is a too specific assumption.  If any I
would only put this in a subclass or a wrapper class.

Finally I believe you are working too much with Arrays.  For example
in method #+ instances of Row, Column and RubyExcel are converted to
Arrays before they are appended.  Since these classes belong to this
library you know how their internals look and you should have a better
way to transfer their data over to this sheet.  Same for #- and
probably others as well.

Kind regards

robert
