great stuff. I came across one issue. When defining margins
oWS.page_margins.right = float(u"1.0"), Excel-2010 flags an error that it can not read the file anymore. When digging into the xml files I found out that openpyxl
whereas if I write an xlsx out of the tool the xml looks like
<pageMargins left="1.00" />
I observed this for versions 1.5.8 and 1.6.1 on Vista-32.
Root cause is that the pageMargins are written using tag() (writer\worksheet.py) which is built as a sequence of start_tag() and end_tag() (in shared\xmltools.py)
To my limited xml-knowledge the generated code looks ok but Bill Gates seems to
have a different opinion.
Best regards and thanx for your great work
