Title with spaces & print title causes excel error
*Created originally on Bitbucket by [pmichalo (Michal)](https://bitbucket.org/%7B8c328135-bbbb-4cb7-a6af-4c28e576f151%7D/)* When I create xlsx file and set worksheet's title with spaces inside and then I am trying to add print title rows this way: ``` #!python ws.print_title_rows = '1:1' ``` I get exception from MSExcel. I look into xml and see this ``` #!xml <definedName localSheetId="3" name="_xlnm.Print_Titles"> 'title with spaces!1:1' </definedName> ``` I suppose that closing quotation mark is in wrong place, I think it should be just before exclamation mark ``` #!xml 'title with spaces'!$1:$1 ``` I use Python 2.7 and openpyxl 2.4.1
