Here is a possible option:
Add a column to your spreadsheet called โStatusโ.
Regenerate your table
Make this row hidden (uncheck the โShowโ option)
Make the initial value = โEditableโ
Make sure the column does not reset on edit
Go in each row, and make the Editable expression = [Status]=โEditableโ
Create an action that changes data in this row
Select the column โStatusโ, and put in the value โNot editableโ
Go to UX < Views, and search for the _Form view of your table
Go to โBehaviorโ in this view
Add the action to be triggered when the form is saved
Now, it will be editable only the first time.
Another possibly easier option:
Go to behavior > Actions
Find the system Edit button for that table view
Show it only if your first column ISBLANK: ISBLANK[Column 1]. That way, when you save, the column will not be blank, the expression will return false, and the edit button will not show when the first column has been filled out.
