Create Table Using Tkinter

Creating a table in Tkinter can be achieved using multiple methods. One common approach is to use a combination of Label and Frame widgets. Another approach is using the ttk.Treeview widget, which offers table-like features.

In this tutorial, I will guide you through creating a basic table using both methods:

1. Using Label and Frame:

  1. Setting up the basic GUI with Tkinter:

    import tkinter as tk

root = tk.Tk()
root.title("Table with Label & Frame")

  2. Function to create table:

    def create_table(rows, cols, data):
    for i in range(rows):
        for j in range(cols):
            label = tk.Label(root, text=data[i][j], borderwidth=1, relief=tk.SOLID)
            label.grid(row=i, column=j, sticky="nsew")

    for i in range(rows):
        root.grid_rowconfigure(i, weight=1)
    for j in range(cols):
        root.grid_columnconfigure(j, weight=1)

  3. Create table data and call the function:

    data = [
    ["Name", "Age", "Country"],
    ["Alice", "25", "USA"],
    ["Bob", "30", "UK"],
    ["Charlie", "35", "Canada"]
]

create_table(4, 3, data)

  4. Run the main loop:

    root.mainloop()

2. Using ttk.Treeview:

  1. Setting up the basic GUI with Tkinter and ttk:

    import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.title("Table with ttk.Treeview")

  2. Function to create table:

    def create_table_with_treeview(data):
    tree = ttk.Treeview(root, columns=list(data[0].keys()), show="headings")

    for col in data[0].keys():
        tree.heading(col, text=col)
        tree.column(col, width=100)

    for item in data:
        tree.insert("", "end", values=list(item.values()))

    tree.pack(pady=20, padx=20)

  3. Create table data and call the function:

    data = [
    {"Name": "Alice", "Age": "25", "Country": "USA"},
    {"Name": "Bob", "Age": "30", "Country": "UK"},
    {"Name": "Charlie", "Age": "35", "Country": "Canada"}
]

create_table_with_treeview(data)

  4. Run the main loop:

    root.mainloop()

The first approach using Label and Frame provides a basic way of displaying data in a tabular format. However, if you need more advanced table features like columns sorting, better interactivity, and scalability for larger datasets, the ttk.Treeview approach is recommended.

  1. Python Tkinter grid table example:

    • Description: Create a simple grid table in Tkinter using labels or entry widgets arranged in a grid.
    • Code Example:
      import tkinter as tk

root = tk.Tk()
root.title("Tkinter Grid Table Example")

# Create a grid table using labels
for i in range(5):
    for j in range(5):
        label = tk.Label(root, text=f"Row {i}, Col {j}", borderwidth=1, relief="solid")
        label.grid(row=i, column=j, padx=5, pady=5)

root.mainloop()

  2. Tkinter treeview table example:

    • Description: Use the Tkinter ttk.Treeview widget to create a table with headers and rows.
    • Code Example:
      import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.title("Tkinter Treeview Table Example")

# Create a Treeview table
tree = ttk.Treeview(root, columns=('Name', 'Age', 'City'))
tree.heading('#0', text='ID')
tree.heading('Name', text='Name')
tree.heading('Age', text='Age')
tree.heading('City', text='City')

tree.insert('', 'end', values=('John Doe', 25, 'New York'))
tree.insert('', 'end', values=('Jane Smith', 30, 'San Francisco'))

tree.pack()

root.mainloop()

  3. How to create a table in Tkinter:

    • Description: Create a table in Tkinter using various widgets like labels or entry widgets arranged in a grid.
    • Code Example:
      import tkinter as tk

root = tk.Tk()

# Create a table using labels
for i in range(5):
    for j in range(5):
        label = tk.Label(root, text=f"Row {i}, Col {j}", borderwidth=1, relief="solid")
        label.grid(row=i, column=j, padx=5, pady=5)

root.mainloop()

  4. Tkinter table with headers and rows:

    • Description: Create a table in Tkinter with headers and rows using labels or entry widgets arranged in a grid.

headers = ['Name', 'Age', 'City']
for j, header in enumerate(headers):
    label = tk.Label(root, text=header, borderwidth=1, relief="solid")
    label.grid(row=0, column=j, padx=5, pady=5)

# Create rows
data = [
    ['John Doe', 25, 'New York'],
    ['Jane Smith', 30, 'San Francisco']
]
for i, row in enumerate(data, start=1):
    for j, value in enumerate(row):
