我在tabulate中使用熊猫，然后在tkinterhtml中插入Tkinter窗口中有很好的经验。

在创建表时，表中甚至所有类型的格式和对齐方式都具有制表符“ stralign”和“ numalign”，甚至“ floatfmt”。

用法示例：

from tabulate import tabulate
from tkinterhtml import HtmlFrame

html = tabulate(df, 
                headers='keys',
                floatfmt=",.1f", tablefmt='html',
                numalign='center', stralign='center')
top = tk.Toplevel()
hf = HtmlFrame(top)
hf.pack()
hf.set_content(html)
