Table Parameter Overrides Not Used When Creating DynamoDB Table

首先检查包含 ActivitiesTable、其 Table 参数和 ListActivitiesFunctionRole 的 SAM 模板，然后使用非默认表名通过 sam build 和 sam deploy --guided 复现。完成标准是：已部署的函数可以扫描该表，并且端点显示空屏幕，而不是抛出 Access denied exception。

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. sam build
2. sam deploy --guided
3. invoke URL from Curl or browser, value found on GET resource in API Gateway console
4. when prompted for table name, use another value like FBActivities or CodeActivities, rather than default of Activities

You will see "internal server error", and CloudWatch

/aws/lambda/crud-sam-app-ListActivitiesFunction-kVMgyUAS17TY
"Access denied exception when calling Scan operation." ListActivitiesFunctionRole.
arn:aws:dynamodb:us-east-1:654654165497:table/FBActivities

Expected behavior
Should show empty screen
