使用 xlsxwriter 和 pandas 创建重叠的边框颜色

Question

给定以下数据：

import pandas as pd
import numpy as np
# sample data
np.random.seed(1)
np.random.seed(1)
df = pd.DataFrame(
    np.random.randint(low=0, high=1000, size=(6, 5)),
    columns=["X", "a", "b", "c", "d"],
    index=["a", "b", "X", "d", "e", "X"],
)

我可以使用以下方法创建一个带有格式化边界的 xlsx 文件：

with pd.ExcelWriter("testing.xlsx") as writer:
    #  need to create xlsx output for this example
    sheet_name = "Sheet1"
    df.to_excel(writer, sheet_name=sheet_name)
    workbook = writer.book
    worksheet = writer.sheets[sheet_name]

    # create horizontal line
    row_range = (3, 3)
    col_range = (1, 8)
    worksheet.conditional_format(
        row_range[0],
        col_range[0],
        row_range[1],
        col_range[1],
        {
            "type": "no_errors",
            "format": workbook.add_format(
                {
                    "top": 2,
                    "border_color": "red",
                }
            ),
        },
    )
    # create vertical line
    row_range = (1, 9)
    col_range = (4, 4)
    worksheet.conditional_format(
        row_range[0],
        col_range[0],
        row_range[1],
        col_range[1],
        {
            "type": "no_errors",
            "format": workbook.add_format(
                {
                    "left": 2,
                    "border_color": "red",
                }
            ),
        },
    )

但是格式不正确（或不符合要求），看起来像：

不正确的部分是：

似乎我无法格式化单元格两次？这是一个问题。

这个问题可以概括为从创建重叠边界到创建重叠条件格式，我对 xlsxwriter 说得不够熟悉。

Answer 1

我找到了解决方法，因为它看起来像一个错误，而且我不是该模块的作者。

这个想法是不要让单元格重叠。我将 2 个范围分成 5 个范围。位于十字路口的单元格有 2 个边框。

import pandas as pd
import numpy as np
# sample data
np.random.seed(1)
np.random.seed(1)
df = pd.DataFrame(
    np.random.randint(low=0, high=1000, size=(6, 5)),
    columns=["X", "a", "b", "c", "d"],
    index=["a", "b", "X", "d", "e", "X"],
)

with pd.ExcelWriter("C:\\Users\\kemot\\Desktop\\programy Python\\testing.xlsx") as writer:
    #  need to create xlsx output for this example
    sheet_name = "Sheet1"
    df.to_excel(writer, sheet_name=sheet_name)
    workbook = writer.book
    worksheet = writer.sheets[sheet_name]

 
   # create horizontal line
    worksheet.conditional_format(
        'A4:B4',
        {
            "type": "no_errors",
            "format": workbook.add_format(
                {
                    "bottom": 2,
                    "border_color": "red",
                }
            ),
        },
    )

    worksheet.conditional_format(
        'C4',
        {
            "type": "no_errors",
            "format": workbook.add_format(
                {
                    "right": 2,
                    "bottom": 2,
                    "border_color": "red",
                }
            ),
        },
    )

    worksheet.conditional_format(
        'D4:F4',

                    "border_color": "red",
                }
            ),
        },
    )
    # create vertical line

    worksheet.conditional_format(
        'D1:D3',
        {
            "type": "no_errors",
            "format": workbook.add_format(

                    "border_color": "red",
                }
            ),
        },
    )

    worksheet.conditional_format(
        'D5:D10',
        {
            "type": "no_errors",
            "format": workbook.add_format(
                {
