How to Create a Flask Table in Python Using MSSQL

Flask Python is a strong and adaptable framework that has arisen in the dynamic field of web development. Together with MSSQL databases’ efficiency, developers can create dynamic, interactive web applications. The design and maintenance of tables is an essential component of web development, as they are essential for the organization and presentation of data.

The foundation of a website’s data representation is its Flask Tables. Flask Tables offer a structured and aesthetically pleasing approach to exhibit information, whether it’s showcasing items, user data, or any other dataset. This post will explain how to easily construct tables using Flask Python and MSSQL.

Set up your Flask application

First, we must install Flask and the necessary libraries to get our project started. To maintain dependencies organized, it is advised to use a virtual environment.

from flask import Flask,render_template, request, redirect, url_for, flash, session
from flask_sqlalchemy import SQLAlchemy
import pyodbc

app = Flask(__name__)

Flask and MSSQL Database Connection

Setting up a connection between Flask and the MSSQL database is essential before creating any Flask Tables. This entails setting up the database schema and configuring the Flask application. Make that the libraries required for seamless communication between the two are installed.

My_cannection = 'DRIVER={ODBC Driver 17 for SQL Server};' \
                   'SERVER=ServerName;' \
                   'DATABASE=dbName;' \
                   'UID=uid;' \

connect_data = pyodbc.connect(My_cannection)

app.config["SQLALCHEMY_DATABASE_URI"] = 'mssql+pyodbc:///?odbc_connect=       {}'.format(connect_data)

app.config['SECRET_KEY'] = 'your_secret_key'

db = SQLAlchemy(app)

Defining the Database Model Class

The database model in Flask establishes our data’s structure. We’ll look at how to define the fields and relationships in a model for our table.

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True, nullable=False)
    name = db.Column(db.String(80),  nullable=False)
    password = db.Column(db.String(80),  nullable=False)
    email = db.Column(db.String(80),  nullable=False)
    image = db.Column(db.String(80),  nullable=False)

Route for Table Design in Flask Python

def index():
    users = User.query.all()
    return render_template('index.html', users=users)

if __name__ == '__main__':

Creating HTML and CSS for Flask Table Structure

A website’s front-end architecture is made up of HTML and CSS. Creating visually beautiful and responsive tables requires a basic understanding of HTML table structure and CSS table styling. We will examine HTML and CSS fundamentals to lay the groundwork for our Flask Python table.

After the database model is set up, we will use HTML to design and CSS to style the Flask Tables structure. To get the desired appearance and feel of the table on the website, this step is essential.

Front-end technologies interface with Flask Table with ease. We’ll link the Flask application to our HTML and CSS files to make sure the data is shown consistently.

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="{{ url_for('static', filename='style.css') }}">
    <title>Flask MSSQL Table</title>
    <h1>User Table</h1>
        {% for user in users %}
                <td>{{ }}</td>
                <td>{{ user.username }}</td>
                <td>{{ }}</td>
               <td>{{ user.password }}</td>
              <td>{{ }}</td>
              <td>{{ user.image }}</td>
        {% endfor %}
body {
    font-family: Arial, sans-serif;

table {
    width: 100%;
    border-collapse: collapse;
    margin-top: 20px;

th, td {
    border: 1px solid #ddd;
    padding: 8px;
    text-align: left;

th {
    background-color: #f2f2f2;
