I have scripted a button to create a new row to my table. It works great when I just use my laptop or HMI but they don't share the data. When I save the project on my laptop the entire table on the HMI disappears. Is there a way to save the information so that this issue does not occur? I am trying to avoid making a database and writing to it but if that is my only option I will look into doing that.

Sounds like you want the data to persist on all sessions? That would be a perfect use case for a memory dataset tag.

How would I go about doing that?

Create a memory tag of type dataset, bind the data parameter of your table to that tag.  
Make sure to select the "Bidrectional" option - this will alow you to use your current logic to update the tag value.
