【Python】命令行表格渲染器 v0.1.0
本帖最后由 ckblt 于 2022-2-1 15:06 编辑我改进了一下我的表格渲染器，
给大家分享一下。{:10_298:}
特别感谢@python爱好者. 的建议与支持！

使用方法:
用 Table.random_table(列表长度, 列表宽度) 来创建一个二维列表
用 t = Table(你的二维列表) 来创建表格
用 t.render() 来渲染
用 t.chart() 来以图表方式渲染
例子:
l = Table.random_table(3, 3)# 创建一个 3x3 的随机二维数组
t = Table(l)# 创建一个表格
print(t.render())
print("分隔线")
print(t.chart())
输出:
2139 3152 757
3783 2615 8039
1156 6488 9565
