Table cell's width to CSS conversion is missing

[zluspai]

Dear Jason,

I was using the PropertyFactory.createProperties(TcPr tcPr) to convert Word's table cell properties to CSS, and noticed that this does not pick up the cell's width.

So I've added my own conversion class which does this, handles percentage and pixel/dxa widths. Not complete though, I don't know how this works with XslFO !!!

There is one question: in my experiences the dxa width was somehow correct if I was dividing the dxa value by 15 instead of the "official" value of 20. Why this is happening here? So fix this if you don't see this is correct????

Thanks
Zoltan
