Traceback error in creating columns in tkintertable-CodePudding

My intent is to create a table with columns only, this is my code:

            tframe = Frame(auto_publish_frame)
            tframe.place(x=0, y=285, height=150, width=500)

            model = TableModel()

            table = TableCanvas(tframe, model, read_only=True, cellwidth=116, rowheight=25, rowheaderwidth=30,
                                cellbackgr='#e3f698',
                                thefont=('Arial', 12), rowselectedcolor='#e4f1fe')
            table.createTableFrame()
            table.addColumn(newname='File')

and I get this type of error:

Traceback (most recent call last):
  File "C:\Users\39377\anaconda3\lib\tkinter\__init__.py", line 1892, in __call__
    return self.func(*args)
  File "C:\Users\39377\anaconda3\lib\site-packages\tkintertable\Tables.py", line 2451, in handle_mouse_move
    if x > self.tablewidth w:
AttributeError: 'ColumnHeader' object has no attribute 'tablewidth'

What's the problem?

You never set this attribute to your table. Maybe you are missing the syntax self. before or you entirly dosent do it or you may set it in a function that isnt called. Without a minimal reproducible example you make me guess.

class ExampelA():
    def __init__(self):
        self.tablewidth = 500
class ExampelB():
    def __init__(self):
        return None
    def set_tablewidth(self):
        self.tablewidth = 500
class ExampelC():
    def __init__(self):
        tablewidth = 500
a = ExampelA()
b = ExampelB()
c = ExampelC()
#print(a.tablewidth)
#print(b.tablewidth)
#print(c.tablewidth)
b.set_tablewidth()
#print(b.tablewidth)

delete a hash symbol and see what happens. ExampleA is the way I tried to tell you in the comments.

Here this is the part that interests you:

class MainPage:

    def __init__(self, root):
        self.root = root
        self.is_login = 0
        self.root.title("Instagram Tool")
        self.root.geometry("1200x600")
        self.root.resizable(False, False)

        # Create main menu frame
        frame_menu = Frame(self.root, bd=0, bg="black")
        frame_menu.place(x=0, y=0, height=600, width=300)
        
        '''other code'''
        # Auto publish button
        auto_publish_button = Button(frame_menu, text="Auto publish", command="set")
