@ghiewa It looks like tktable is not installed.

[yashkark]

Try installing the tk-table package.

sudo apt-get install tk-table (for linux use the respective windows command)

Worked for me

@yashkark I tried to install the package and it did not work. Please advise how to install the package and I am using anaconda. I t made me crazy. Thank you very much.

[nbro]

@Goujun Which operating system are you using exactly?

sudo apt-get install tk-table only works on a few Linux distros.

By the way, I am not sure if using Anaconda is going to cause you problems, given that I am not sure if Anaconda distribution of Python actually supports or not tkinter. Have you checked if there are table libraries specifically for Anaconda?

[Goujun]

@nbro , thank you for your reply and I am using Windows 10 and anaconda environment.

[yashkark]

@Goujun If that is not working you can just download the tktable.py file put it in the same folder as your project and import tktable.

[Goujun]

@yashkark I tried that method, however, it gave me the same error, that is very weird. That was why I tried to install the package. Sorry to trouble you.

[nbro]

@Goujun What @yashkark is suggesting doesn't work if the underlying Tcl/Tk implementation does not have the tktable (written in Tcl/C) installed.

This Python library is a "wrapper" library around the Tcl/Tk tktable library, that is, this library is a bunch of functions and classes to access another library (written in another language different from Python), which you first need to install!

[yashkark]

@Goujun

import Tkinter as tk
import tktable

def table_test():

    #### DEFINES THE GUI ####
    master = tk.Tk()
    master.geometry('800x800+250+200')
    master.title('Dogs')

    #### SETS THE DOG INTO THE TABLE ####
    def callback_dogs(event):
        values = ['Doodle','Pug','Westie','Poodle']
        for item in values:
            return item

    #### DEFINING THE TKTABLE ####
    tb = tktable.Table(master, state='disabled', width=15, titlerows=1, rows=3, cols=2, command=callback_dogs)
    tb.pack(expand=1)

    #### MAINLOOPING ####
    master.attributes('-topmost',True)
    master.after_idle(master.attributes,'-topmost',False)
    tk.mainloop()

table_test()

This worked for me. If it is not for you try using something else. What exactly are you looking to do? You can try out the Tkinter treeview.

[nbro]

@yashkark Yes, but this means that you already had the underlying Tk library tktable installed, otherwise that code would give you an error.

[Goujun]

@nbro Thank you for your advice and does that mean I need to install new Tcl/Tk which support tktable library first?
@yashkark, thank you very much, I want to implement the automation test which allows me to do tasks in parallel. I want to grab data from instruments and show them on the screen, after the test completes, I will save the data.

[nbro]

@Goujun Yes, exactly. Sorry for this late reply: I hope you were able to solve your problem meanwhile.
