在 Python 3 中使用 xlsxwriter 交替行颜色 [英] Alternating row color using xlsxwriter in Python 3

问题描述

有没有人在 Python3 中使用 xlsxwriter 生成 excel 时实现交替行颜色?

Has anybody implemented alternating row color while generating excel using xlsxwriter in Python3?

data_format = workbook.add_format(
    {
        'bg_color': '#FFC7CE'
    })

worksheet.write(data_row, data_col + 1, row[1], data_format)

这将设置每列的颜色.

推荐答案

没有什么可以阻止您手动设置格式，如下所示.有两种方法:

There is nothing stopping you from setting the formats manually as follows. There are two approaches:

1. 使用 .add_format() 为每一行添加格式.

使用 .add_table() 使用 Excel 表格添加数据.此样式允许自动带状行.这也有一个好处，如果表被排序，则条带不受影响.

Add the data using an Excel table using .add_table(). The style for this allows for automatic banded rows. This also has the advantage that if the table is sorted, the banding is unaffected.

上下文管理器可用于事后自动关闭工作簿.

A context manager can be used to automatically close the workbook afterwards.

方法 1:

手动将单元格格式应用于每一行:

Manually applying a cell format to each row:

import xlsxwriter

with xlsxwriter.Workbook('hello.xlsx') as workbook:
    worksheet = workbook.add_worksheet()

    data_format1 = workbook.add_format({'bg_color': '#FFC7CE'})
    data_format2 = workbook.add_format({'bg_color': '#00C7CE'})

    for row in range(0, 10, 2):
        worksheet.set_row(row, cell_format=data_format1)
        worksheet.set_row(row + 1, cell_format=data_format2)
        worksheet.write(row, 0, "Hello")
        worksheet.write(row + 1, 0, "world")

这将为您提供如下所示的输出:

This would give you output looking as follows:

要将其应用于数据列表，您可以使用以下方法.这也显示了如何扩展它以使用其他格式:

To apply this to a list of data, you could use the following approach. This also shows how it could be extended to use additional formats:

import xlsxwriter
from itertools import cycle

data = ["Row 1", "Row 2", "Row 3", "Row 4", "Row 5", "Row 6"]

with xlsxwriter.Workbook('hello.xlsx') as workbook:
    data_format1 = workbook.add_format({'bg_color': '#EEEEEE'})
    data_format2 = workbook.add_format({'bg_color': '#DDDDDD'})
    data_format3 = workbook.add_format({'bg_color': '#CCCCCC'})
    formats = cycle([data_format1, data_format2, data_format3])
    
    worksheet = workbook.add_worksheet()

    for row, value in enumerate(data):
        data_format = next(formats)

        worksheet.set_row(row, cell_format=data_format)
        worksheet.write(row, 0, value)

方法 2:

使用带条带样式的 .add_table() 添加数据:

Adding the data using .add_table() with a banded style:

import xlsxwriter

data = [["Row 1"], ["Row 2"], ["Row 3"], ["Row 4"], ["Row 5"], ["Row 6"]]

with xlsxwriter.Workbook('hello.xlsx') as workbook:
    worksheet = workbook.add_worksheet()
    worksheet.add_table('A1:A6', {'data' : data, 'header_row' : False})

Excel 带有许多不同的预定义表格样式，可以通过传递一个 style 参数来选择这些样式，如下所示:

Excel comes with a number of different pre-defined table styles, these can be selected by passing a style paramter as follows:

'style': 'Table Style Light 11'
