Add styles to table cell element

[SLSCoder58]

I'm interested in helping solve this and realize a pull request was made but never implemented.
I can't figure out how to add styles to an element.
For example, Styles/TextBox.php includes the property: innerMarginRight.
How does that property end up being used in a Word doc?
I see in Writer/Word2007/Style/Cell.php line 59 this: w:textDirection
I understand what textDirection is but have no idea how it ends up in a Word element.
How can I learn what this means and how it translates into a property in a Word element?
How can I learn what other properties (ie Margin; Padding) are possible that Word would recognize?

I'd really appreciate it if somebody would point me in a direction so I can add margins and padding to tables and cells.
