将tableView数据移动到另一个具有单独实体名称的tableView

I am trying to use a button to move an entire section of my tableView at once. I want it to move all of the selected rows to another tableView and delete them from the first. The first tableView data is saved in SList the second is SCList. Both Entities have attributes item, qty, desc just the first letters change from sl to sc (i.e. slitem to scitem). The problem I am having is getting the data to change from the SList entity to the SCList entity. How do I get it to remove the data from SList entity and change to SCList and add it to the respective tableView?I am trying to use a button to move an entire s
