In this example, a Tkinter table is used as an interface to display data in an SQLite database table: from tkinter import ttk import tkinter as tk import sqlite3 def connect(): con1 = nnect(" ") cur1 = con1.cursor() cur1.execute("CREATE TABLE IF NOT EXISTS table1(id INTEGER PRIMARY KEY, First TEXT, Surname TEXT)") mit() con1.close() def View(): con1 = nnect(" ") cur1 = con1.cursor() cur1.execute("SELECT * FROM ") rows = cur1.fetchall() for row in rows: print(row) tree.insert("", tk.END, values=row) con1.close() # connect to the database connect() root = tk.Tk() tree = ttk.Treeview(root, column=("c1", "c2", "c3"), show='headings') lumn("#1", anchor=tk.CENTER) tree.heading("#1", text="ID") lumn("#2", anchor=tk.CENTER) tree.heading("#2", text="FNAME") lumn("#3", anchor=tk.CENTER) tree.heading("#3", text="LNAME") tree.pack() button1 = tk.Button(text="Display data", command=View) button1.pack(pady=10) root.mainloop() How to Display Pandas and Numpy Data in a Tkinter Table Note that the data displayed in the Tkinter table is not persistent, but the query statement is saved automatically in the database for future use. # An SQL statement that selects all data from a table: SELECT * from In this case, an SQL statement is typically used to select all or some of the data in one or more database tables for display in the table. In this example, the range() function generates a list of numbers based on a grid formula of row " for cj in range(4)] for ri in range(1)]) # table enable choices listed below: sheet.enable_bindings(("single_select", "row_select", "column_width_resize", "arrowkeys", "right_click_popup_menu", "rc_select", "rc_insert_row", "rc_delete_row", "copy", "cut", "paste", "delete", "undo", "edit_cell")) top.mainloop() How to Display SQLite Data in a Tkinter TableĪ Tkinter table can serve as an interface for data located in permanent storage, such as an SQLite database. The Tksheet package can be installed in a terminal or command line, by entering: pip install tksheet Row and column coordinates ( x:y ) are displayed in each cell by default, and can be replaced with other data. It provides a Tkinter table widget with many options including a popup (right-click) menu that lets you add and delete rows, edit data in cells, and undo changes. Tksheet is a third party package available in PyPI. In this example, the range() function generates a list of numbers which are populated into an Entry widget table of 5 rows and 4 columns arranged in a grid() layout: from tkinter import * rows = for i in range(5): cols = for j in range(4): e = Entry(relief=GROOVE) e.grid(row=i, column=j, sticky=NSEW) e.insert(END, '%d.%d' % (i, j)) cols.append(e) rows.append(cols) mainloop() How to Display Data in a Tkinter Tksheet Widget Table ![]() ![]() An Entry widget is typically used to enter or display a single string of text, but it can also be used together with the range() function and for loop to display values in a table of multiple rows and columns.
