如何使用matplotlib绘制表格

import matplotlib.pyplot as plt
from matplotlib.table import Table

data = [['', 'Col1', 'Col2', 'Col3'],
        ['Row1', 1, 2, 3],
        ['Row2', 4, 5, 6],
        ['Row3', 7, 8, 9]]

table = Table(plt.gca(), bbox=[0, 0, 1, 1])  # plt.gca()获取当前坐标轴，bbox用于指定表格的位置和尺寸

# 设置表格的行标题和列标题
for i, row in enumerate(data):
    for j, cell in enumerate(row):
        if i == 0:
            table.add_cell(i, j, width=0.1, height=0.1, text=cell, loc='center', facecolor='gray')
        else:
            table.add_cell(i, j, width=0.1, height=0.1, text=cell, loc='center')

# 设置表格的行和列的边框样式
for i in range(len(data)):
    table.add_cell(i, -1, width=0.1, height=0.1, text='', loc='right', edgecolor='none')
for j in range(len(data[0])):
    table.add_cell(-1, j, width=0.1, height=0.1, text='', loc='center', edgecolor='none')

# 设置表格的单元格边框样式
for i in range(1, len(data)):
    for j in range(len(data[0])):
        table.add_cell(i, j, width=0.1, height=0.1, text='', loc='center', edgecolor='black')

plt.axis('off')  # 隐藏坐标轴
plt.title('Table Example')  # 设置图表标题
plt.show()  # 显示图表
