Limited amount of data entries displayed in Tkinter table

Question

I'm currently creating database for a school with 90 students. When testing out the function that displays all database entries in a table, I've found that only 10 entries can be displayed in the table at one time. Is there any way I can extend or remove this limit?

    def DataTable():
            def View():

                for row in db_actions.GetAllStudents():
                    print(row)
                    tree.insert("", tk.END, values = row)


            tree = ttk.Treeview(TableView, column=("c1", "c2", "c3", "c4"), show='headings')

            tree.column("#1", anchor='center')

            tree.heading("#1", text="Number")

            tree.column("#2", anchor='center')

            tree.heading("#2", text="First name")

            tree.column("#3", anchor='center')

            tree.heading("#3", text="Surname")

            tree.column("#4", anchor='center')

            tree.heading("#4", text="Class")

            tree.pack()

            View()
    DataTable()

The role of

for row in db_actions.GetAllStudents():

is to retrieve data from a database in another program. I have tested this and the issue is unlikely to be database-related due to the program working perfectly when there's less than 10 entries.
