python中tksheet库里怎么读取指定行单元格背景色

tksheet库似乎没有提供读取指定行单元格背景色的方法，但可以通过以下步骤实现：

1. 获取表格的所有单元格背景色

bg_colors = sheet.get_all_bg_color_data()

2. 获取指定行的所有单元格背景色

row_bg_colors = bg_colors[row_index]

3. 获取指定单元格的背景色

cell_bg_color = row_bg_colors[cell_index]

完整代码示例如下：

import tkinter as tk
from tksheet import Sheet

# create sheet
root = tk.Tk()
sheet = Sheet(root)
sheet.create_sheet(10, 10)

# set cell background color
sheet.set_bg_color_data("A1", "red")
sheet.set_bg_color_data("B2", "blue")
sheet.set_bg_color_data("C3", "green")

# get all cell background colors
bg_colors = sheet.get_all_bg_color_data()

# get row 1 cell background colors
row_index = 1
row_bg_colors = bg_colors[row_index]

# get cell (1, 1) background color
cell_index = 1
cell_bg_color = row_bg_colors[cell_index]

print(cell_bg_color)  # output: blue

root.mainloop()
