为什么我不能填充tksheet表行？

如何解决为什么我不能填充tksheet表行？

1. 我正在尝试使用python建立学生的出勤记录。我大部分都想通了。我被困在一个部分，这是与会者部分。我正在尝试使用表格格式（tksheets）来记录学生姓名和出勤情况。我遇到的问题正在使用tksheets。我似乎无法从DB（SQLite3）中获取信息来填充列。我也尝试过tktables和pandastables。但是我又遇到了同样的问题。

我已经考虑过使用Treeview小部件用学生姓名填充列，然后使用输入框添加出勤率。问题是我必须创建每个输入框并分别放置。我不喜欢这个计划。下面是我正在使用的当前代码。

如果有人可以告诉我如何从数据库中获取数据并填充电子表格，那将是很棒的选择。谢谢。

    def rows(self):
        self.grid_columnconfigure(1,weight=1)
        self.grid_rowconfigure(1,weight=1)
        self.sheet = Sheet(self.aug_tab,data=[[f'Row{r} Column{c}' for c in range(36)]for r in range(24)],height=300,width=900)
        self.sheet.enable_bindings(("single","drag_select","column_drag_and_drop","row_drag_and_drop","column_select","row_select","column_width_resize","double_click_column_resize","row_width_resize","column_height_resize","arrowkeys","row_height_resize","double_click_row_resize","right_click_popup_menu","rc_insert_column","rc_delete_column","rc_insert_row","rc_delete_row","copy","cut","paste","delete","undo","edit_cell"))
           

        self.headers_list = ("Student ID","Ch. First Name","Ch. Last Name","Eng. Name")
        self.headers = [f'{c}'for c in self.headers_list]
        self.sheet.headers(self.headers)

        self.sheet.pack()
        print(self.sheet.get_column_data(0,0))

解决方法

“”“好，您应该在代码和按钮中添加一个功能，同时您可以一个一个地插入您的学生姓名或将大量您的学生姓名复制到表格中，这是我的代码”“”

from tksheet import Sheet
import tkinter as tk


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0,weight = 1)
        self.grid_rowconfigure(0,weight = 1)
        self.sheet_demo = Sheet(self,height = 500,width = 700) 
        self.sheet_demo.enable_bindings(("single","drag_select","column_drag_and_drop","row_drag_and_drop","column_select","row_select","column_width_resize","double_click_column_resize","row_width_resize","column_height_resize","arrowkeys","row_height_resize","double_click_row_resize","right_click_popup_menu","rc_insert_column","rc_delete_column","rc_insert_row","rc_delete_row","copy","cut","paste","delete","undo","edit_cell"))
    
        self.sheet_demo.grid(row = 0,column = 0,sticky = "nswe")
    
 
        self.data = [[f"" for c in range(1)] for r in range(100)]
        self.sheet_demo.data_reference(self.data)
    

        def click_this():
            for i in (self.sheet_demo.get_column_data(0)): 
                if i == '':
                break
                else:
                    print(i.strip())
                    self.data = [[f"" for c in range(1)]for r in range(100)]
                    self.sheet_demo.data_reference(self.data)
                
        button=tk.Button(text=" click this",command= click_this)
        button.grid(row= 1,column=0,sticky= "n")


    
app = demo()
app.mainloop()
