Missing column width causes load_workbook() exception

Issue #300 resolved
Mark Brighton
created an issue

I've encountered an exception (traceback below) when trying to open an xlsx file that was created by Google docs (attached trivial sample). It appears that some of the column elements don't have a width attribute. This causes ColumnDimensions.init() to throw a type error when it tries to call float(None)

It seems like the simple solution is to change that line to catch the exception and set width to -1 (the default in the method signature).

This exception happens when load_workbook() is called with use_iterators=False (the default). If it's called with use_iterators=True, then only a warning is emitted.

I'm using Python 2.7.6 and openpyxl 1.8.5.

Cheers.
