Sorry TAG.whatever is not serializable with pickle. You can only serialize it after converting to string with srt(). > Second, the TABLE helper doesn't seem to treat colgroup > appropriately... > > >>> table = TABLE(TAG.colgroup(),THEAD(),TBODY()) > >>> print table > > <table><tr><td><colgroup></colgroup></td></tr><thead></thead><tbody></ > tbody></ta > ble> > > When something like this would seem the preferable result... > > <table><colgroup></colgroup><thead></thead><tbody><tr><td></td></tr></tbody></table> TABLE is too smart but does not know about colgroup. You can do table = TAG.table(TAG.colgroup(),THEAD(),TBODY()) > I know the work-around is to split it into two steps with "table.insert (0,TAG.colgroup())", but that does seem a little messy (and then it doesn't pickle anyway). Perhaps a colgroup helper is warranted? You can do it yourself. redefine TABLE=TAG.table COLGROUP=TAG.colgroup serialize it with table.xml().
