---------------------------------------------------------------
I have three problem about "Table API page" in mailing list.
They're all about *old code usage* which is written in the newest documentation.
Could you help solve it?
It's NOT allowed to post question in JIRA,
but nobody in mailing ever answered them.
I guess official developers are too busy.
Thanks for your help.
