Subject RE: ColumnInfo records
Date Tue, 19 Jul 2005 20:53:50 GMT
Peter,

The expected behaviour should be that a cell retains
the style of the column unless a style is explicitly set.
Currently, that is not the case hence possibly a bug (created
issue# 35799).

I have a tentative patch (not thoroughly tested) that works 
so if you are comfortable with building from source and 
applying a local cvs patch, I can send you the patch file.

Regards,
~ amol
