function column_quote Have bug

[mengjie0827]

$last_user_id = $db->insert("userlist", [
"username" => "foo",
"(JSON)userqq" => ["en", "fr", "jp", "cn"]
]);

SQL:
INSERT INTO "userlist" (username, (JSON)userqq) VALUES ('foo', '["en","fr","jp","cn"]')

Can not replace JSON?

column quote pattern is wrong.

protected function column_quote($string)
{
     return preg_replace('/(\(JSON\)\s*|^#)?([a-zA-Z0-9_]*)\.([a-zA-Z0-9_]*)/', '"' . $this->prefix . '$2"."$3"', $string);
}

you must add table name before field name.

$last_user_id = $db->insert("userlist", [
"username" => "foo",
"(JSON)userlist.userqq" => ["en", "fr", "jp", "cn"] 
]);
