A way to adjust row height on tkinter treeview but problem with tkTable

I am using tkinter and tkinter’s treeview. When I started using it, the bottom of characters were chopped off.

I added was able to increase the row height by using a rowheight parameter with ttk.style.

ttk.Style().configure(“Treeview”, background="#FF0FFF",
foreground=“black”, fieldbackground=“blue”, rowheight=40)

However, when I tried to use tkTable I got a jumble of overlapping letters. I tried to import preferences.py but got an error.
