Why should we add another lookup_table? In my mind, we can reuse the old lookup_table_op.

Agree with @jacquesqiao , current lookup_table_op can also use Get to get value from the table if weight is SelectedRows

Hi @typhoonzero @jacquesqiao
Maybe we can't reuse lookup_table_op, because of the table variable is a const Input var in it. We need another new op to implement the Compute(No Kernel Op) so that we can edit the input var.
