If you are linking the tables directly to reports at design time than it might be difficult to change the table at run-time.

There is an alternate approach to do this.
Create a SP that takes Table string as input parameter Ex: "Employee" or "Supplier"
depending upon the parameter either you can have one dynamic SQL returning
ID,Name,Address,PhoneNumber Or a simple If-else statement Ex:

If @TableName="Employee"
select ID,Name,Address,PhoneNumber from employee
else if @TableName="Supplier"
select ID,Name,Address,PhoneNumber from employee
...

Link you report to this SP. Pass the input parameters at run-time & you get the desired result.
