Font and Column width problem

[John Johnson <johnson98 rcn com>]

Hello, 
I've noticed that when I import an excel spreadsheet, neither the fonts
nor the column widths are preserved. For example, if the original font
is Arial, the font is displayed as Helvetica (which is the default
font). Is there a way to preserve the original font type? How do I
change the default font? 

In the case of column widths, the imported spreadsheet column widths are
smaller than the original. What I've noticed is that excel uses number
of characters for column width while gnumeric use pixels or points. Is
this the reason for the difference. Is there a way to properly preserve
column widths. 

Thanks 
John
