ttk.treeview增加标题单击排序功能

1. 排序函数

def treeview_sort_column(tv, col, reverse):    l = [(tv.set(k, col), k) for k in tv.get_children('')]    #i = cols.index(col)    #l.sort(key=lambda t: t[i], reverse=reverse)    l.sort(reverse=reverse)    #      ^^^^^^^^^^^^^^^^^^^^^^^    for index, (val, k) in enumerate(l):        tv.move(k, '', index)    tv.heading(col,command=lambda: treeview_sort_column(tv, col, not reverse))

1. 实现

        for col in cols:            i = cols.index(col)            #self.mat_list.heading(col, text=tree_head[i])            self.mat_list.heading(col, text=tree_head[i] , command=lambda _col=col: treeview_sort_column(self.mat_list, _col, False))
