Tkinter TreeView – Enable Sorting upon Clicking Column Headings

The below code snippet can help you achieve the Sorting Option on Treeview Column Headings in Tkinter in both ascending and descending order.

columns = ("Student","Course","Last Session")

tv = Treeview(popup, show='headings', columns=columns,height=25)

def treeview_sort_column(tv, col, reverse):
    l = [(tv.set(k, col), k) for k in tv.get_children('')]
    l.sort(reverse=reverse)

    # rearrange items in sorted positions
    for index, (val, k) in enumerate(l):
        tv.move(k, '', index)

    # reverse sort next time
    tv.heading(col, command=lambda _col=col: treeview_sort_column(tv, _col, not reverse))

for col in columns:
    tv.heading(col, text=col,command=lambda _col=col: treeview_sort_column(tv, _col, False))
tv.pack()
