Python Fill Table Widget - Python

Python provides a variety of libraries and modules that enable programmers to create user interfaces and applications with ease. One of such modules is the Tkinter module, which is a standard Python interface to the Tk GUI toolkit. In this tutorial, we'll take a look at how to fill a table widget in Python using the Tkinter module.

Prerequisites

Before you begin, make sure you have Python installed on your computer. You can download Python here.

Creating a Table Widget

The first step to filling a table widget in Python is to create the table itself. We'll be using the Tkinter module for this task. Here's the code to create a table widget:

from tkinter import *

root = Tk()

table = Frame(root)
table.pack()

header = ['Name', 'Age', 'Gender']
table_header = Frame(table)
table_header.pack(side=TOP)
for column in header:
    label = Label(table_header, text=column, bg="white", font='Helvetica 10 bold', relief='solid', bd=1)
    label.pack(side=LEFT, padx=2, pady=2)

root.mainloop()

The code above creates a simple three-column table with headers for each column.

Filling the Table Widget

In order to fill the table widget, we need to create a function that will take in data and populate the table accordingly. Here's an example function that does that:

def fill_table(table, data):
    for i, row in enumerate(data):
        current_row = Frame(table)
        current_row.pack(side=TOP, fill=X)

        for j, item in enumerate(row):
            if j == 0:
                label = Label(current_row, text=item, font='Helvetica 9', bd=1, relief='solid', anchor=W, justify=LEFT)
                label.pack(side=LEFT, padx=2, pady=2, expand=YES, fill=X)
            else:
                label = Label(current_row, text=item, font='Helvetica 9', bd=1, relief='solid', anchor=E, justify=RIGHT)
                label.pack(side=LEFT, padx=2, pady=2, expand=YES, fill=X)

    return table

The function fill_table takes in two parameters, table, which is the table widget we created earlier, and data, which is a list of lists representing the data to be displayed in the table. The function iterates over the list of lists and creates labels for each item in the table.

Putting It All Together

Now that we've created a function to fill the table widget, all that's left to do is to call it with our data and display the table. Here's an example:

from tkinter import *

def fill_table(table, data):
    for i, row in enumerate(data):
        current_row = Frame(table)
        current_row.pack(side=TOP, fill=X)

        for j, item in enumerate(row):
            if j == 0:
                label = Label(current_row, text=item, font='Helvetica 9', bd=1, relief='solid', anchor=W, justify=LEFT)
                label.pack(side=LEFT, padx=2, pady=2, expand=YES, fill=X)
            else:
                label = Label(current_row, text=item, font='Helvetica 9', bd=1, relief='solid', anchor=E, justify=RIGHT)
                label.pack(side=LEFT, padx=2, pady=2, expand=YES, fill=X)

    return table

root = Tk()
table = Frame(root)
table.pack()

header = ['Name', 'Age', 'Gender']
table_header = Frame(table)
table_header.pack(side=TOP)
for column in header:
    label = Label(table_header, text=column, bg="white", font='Helvetica 10 bold', relief='solid', bd=1)
    label.pack(side=LEFT, padx=2, pady=2)

data = [['John Doe', '34', 'Male'], ['Jane Doe', '28', 'Female'], ['Bob Smith', '45', 'Male']]
fill_table(table, data)

root.mainloop()

The code above creates a table widget with data to be displayed. The fill_table function takes in the table widget and the data to be displayed, and populates the table widget with that data.

Conclusion

In this tutorial, we've gone over how to fill a table widget in Python using the Tkinter module. We created a table widget with a header, wrote a function to populate it with data, and finally displayed the table widget. You can use these techniques to create more complex table widgets with more features.
