thanks, appreciated :-)

hmm, maybe, afaik there are some possible variations in the xml to 
produce a 'default' col width, possibly one of those isn't covered, It's 
also possible that your test document isn't using a font that is on 
linux ( assuming that you are testing the libreoffice side on linux ) 
Column widths in Excel are measured in units proportional to character 
widths ( as determined by the font used by the default style ) If you 
are using a font that 'calc' doesn't know about then it will for the 
width calculation fallback to some font determined by whatever font 
matching mechanism we use ( I suppose we no longer use that crazy font 
xml file but use fontconfig these days ) and in that case a column width 
on export could be different (especially if the font matched isn't 
property metrically equivalent ). In my testing at least I saw the 
values were as expected when using font I know exists on my windows and 
linux box e.g. using 'Liberation Mono 11 pt' as the font defined for the 
'Normal' style. If doing similar and you still see a problem then by all 
means open a bug against me and I will try and figure out where it is 
going wrong

thanks again
