Can I make a not aligned gtk treeview?

[Binary Chen <binary chen gmail com>]

Hi,

I have a gtktreeview with two column, the first one is pixbuf, the
second one is a string. something happen bad if in a row the first
pixbuf is NULL, so it doesn't occupy any place, but in the following row
there is a pixbuf and occupy some place. the default behavior of
gtktreeview will align the second column so leave a large blank in first
row.

How can I tell treeview not align in different row, but just place the
column independently?

Thanks.
