[web2py] SQLTABLE error using crud.search

[黄祥]

Hi,

I have a problem using crud.search, heres my contoller :

def blog():
    table = db.blog
    search, rows = crud.search(table)
    return dict(search = search, rows = rows)

and my view (blog.html) is :

{{=DIV(search)}}
{{=SQLTABLE(rows, headers='fieldname:capitalize')}}

when there is a parameter it can run, i mean, when i change my view
code like :

{{=DIV(search)}}
{{=DIV(rows)}}

and then change into sqltable and refresh it, it can run, is anyone
knows where is my code's fault?

Thank you so much
