Style improving

[masete17]

Hi!

I have developed a couple of features for syling cells:

Cell border (all borders and part of then: top, bottom, left and/or right) Text wrapping

Please feeback me if you notice something wrong.

Greetings!

I need more time to check the feature, but I will leave some inline-comments about the commit
