time.sleep(0.5)
展示效果：
3. console控制台
为了完全控制终端格式，Rich提供了一个Console类。
from rich.console import Console
console = Console()
在构建Console对象时，你可以选择以下参数：
- size 是终端的当前尺寸（尽量不要手动设置它，因为它是自动的）
- encoding 编码方式
- color_system 颜色空间
- file 当你设置了这个参数，Console的打印将被重定向到指定文件
3.1 使用console.rule()来打印带标题的分隔线
from rich.console import Console
console = Console()
console.print('hellllllo world')
console.rule("[bold red]Chapter 2")
console.print('may the god be with you')
console.print('gigigaga')
3.2 使用console.log()来打印日志
console.log('hello world')
输出：
[19:51:28] hello world
4. 表单
rich.table.Table()的实例为一个具有行和列的可渲染对象
from rich.table import Table
from rich.console import Console
console = Console()
table = Table()
table.add_column('[red]test')
table.add_column('[red]test2')
table.add_row('[red]this is a table', '[yellow]this is a table')
table.add_row('[red]hello', '[yellow]world')
console.print(table)
输出
