要在DataGrid中顯示MySQL數(shù)據(jù)，你需要遵循以下步驟：

  1. 首先確保你已經(jīng)安裝了MySQL數(shù)據(jù)庫，以及Python的MySQL連接器庫。如果沒有安裝，可以使用以下命令安裝：
pip install mysql-connector-python
  1. 創(chuàng)建一個Python腳本，連接到MySQL數(shù)據(jù)庫并執(zhí)行查詢以獲取數(shù)據(jù)。以下是一個示例腳本：
import mysql.connector
from mysql.connector import Error

try:
    # 連接到MySQL數(shù)據(jù)庫
    connection = mysql.connector.connect(
        host='localhost',
        user='your_username',
        password='your_password',
        database='your_database'
    )

    if connection.is_connected():
        cursor = connection.cursor()
        # 執(zhí)行查詢以獲取數(shù)據(jù)
        cursor.execute("SELECT * FROM your_table")
        rows = cursor.fetchall()
        print("數(shù)據(jù)已獲取")
except Error as e:
    print("連接失敗:", e)
finally:
    if connection.is_connected():
        cursor.close()
        connection.close()
        print("數(shù)據(jù)庫連接已關(guān)閉")
  1. 在獲取數(shù)據(jù)后，你可以使用一個Python Web框架（如Flask或Django）來創(chuàng)建一個Web應(yīng)用程序，并在DataGrid中顯示數(shù)據(jù)。以下是一個使用Flask和Bootstrap的簡單示例：
from flask import Flask, render_template
import mysql.connector
from mysql.connector import Error

app = Flask(__name__)

@app.route('/')
def index():
    try:
        # 連接到MySQL數(shù)據(jù)庫
        connection = mysql.connector.connect(
            host='localhost',
            user='your_username',
            password='your_password',
            database='your_database'
        )

        if connection.is_connected():
            cursor = connection.cursor()
            # 執(zhí)行查詢以獲取數(shù)據(jù)
            cursor.execute("SELECT * FROM your_table")
            rows = cursor.fetchall()
            print("數(shù)據(jù)已獲取")
    except Error as e:
        print("連接失敗:", e)
    finally:
        if connection.is_connected():
            cursor.close()
            connection.close()
            print("數(shù)據(jù)庫連接已關(guān)閉")

    return render_template('index.html', rows=rows)

if __name__ == '__main__':
    app.run(debug=True)
  1. 創(chuàng)建一個名為index.html的HTML模板文件，其中包含一個DataGrid，用于顯示MySQL數(shù)據(jù)。以下是一個使用Bootstrap的簡單示例：
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>顯示MySQL數(shù)據(jù)</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</head>
<body>
    <div class="container">
        <h1>顯示MySQL數(shù)據(jù)</h1>
        <table class="table table-striped">
            <thead>
                <tr>
                    <th>列1</th>
                    <th>列2</th>
                    <th>列3</th>
                </tr>
            </thead>
            <tbody>
                {% for row in rows %}
                <tr>
                    <td>{{ row[0] }}</td>
                    <td>{{ row[1] }}</td>
                    <td>{{ row[2] }}</td>
                </tr>
                {% endfor %}
            </tbody>
        </table>
    </div>
</body>
</html>

現(xiàn)在，當(dāng)你運行Python腳本并訪問Web應(yīng)用程序時，你應(yīng)該能在DataGrid中看到MySQL數(shù)據(jù)。
