This is what I use. mapper.local_table.c It seems to give me the columns in the same order as I define them in my Table object. > - I found out that table_name._orig_cols gives me the column names and > types, but as it's in a dict, it's not ordered > > - the repr of a table name gives the Table object, which has the columns > listed in order.

However, this may not give you the ordering of columns which you desire because it's totally up to the database server how the order of the columns are returned when SA queries the metadata. I got around this by mimicking what django does, that is define a inner Admin class on my model classes with similar types of properties as you would find in django to control the layout of tables,forms,lists etc. You don't have to use the inner class but it boils down to have some sort of metadata (whether it's in code,config files,xml etc) to help you auto generate gui stuff. The rich metadata which SA captures is awesome for this type of stuff. Hope that helps.
