如何从数据库中整齐地打印表格

import mysql.connector
from prettytable import PrettyTable

# 连接数据库
cnx = mysql.connector.connect(user='username', password='password',
                              host='localhost', database='database_name')
cursor = cnx.cursor()

# 查询数据
query = "SELECT * FROM table_name"
cursor.execute(query)

# 获取查询结果
result = cursor.fetchall()

# 创建表格对象
table = PrettyTable()
table.field_names = [i[0] for i in cursor.description]

# 添加数据到表格
for row in result:
    table.add_row(row)

# 格式化输出
formatted_table = table.get_string()

# 打印表格
print(formatted_table)

# 关闭数据库连接
cursor.close()
cnx.close()
