Until now, you have been associating your subscription to a table containing a single record.
You could see that in a more general way, by associating your subscription to the record in your table that is identified by a predetermined key (and the key value should be in correspondance with the item name).

Now, in order to subscribe to multiple lines, you should use multiple items and setup multiple lines on your page for displaying the results.
Otherwise, if you want to subscribe to the entire table contents, you could leverage COMMAND mode.
Please see this thread, which explores the former case, first.
Do you think you will need COMMAND mode?
