AutoFill extension

rain

Hello! It’s very difficult for me to deal with the information on installing extensions. If not difficult, please help. I have a WordPress tablepress plugin installed, everything works great. But you really need to add autocomplete. I already asked and they showed me this AutoFill extension. What you need to install additionally, so that it is like in this example https://editor.datatables.net/examples/extensions/autoFill. So far, nothing has worked out for me. Thanks to all!
