DataWorks在maxcompute控制台设置角色权限为为什么该用户还可以删表呢？

DataWorks在maxcompute控制台设置角色权限为{
"Statement": [{
"Action": ["odps:Describe",
"odps:Select"],
"Effect": "Allow",
"Resource": ["acs:odps::projects/project_name/tables/"]},
{
"Action": ["odps:Read",
"odps:Write"],
"Effect": "Allow",
"Resource": ["acs:odps::projects/project_name/resources/"]},
{
"Action": ["odps:Read",
"odps:Write"],
"Effect": "Allow",
"Resource": ["acs:odps::projects/project_name/functions/"]}],
"Version": "1"}
然后在datawork中设置权限为访客，为什么该用户还可以删表呢？
