python__excel__7">python - excel 设置样式

1. 准备

准备一个无样式的excel

生成demo可以看这里
python- excel 创建/写入/删sheet+花式遍历

2. 示例

2.1. 给单元格设置样式"等线"、大小为24磅、斜体、红色颜色和粗体

import os

from openpyxl import load_workbook
from openpyxl.styles import Font, Alignment, Color, Border, Side


def listdir(file_path):
    paths = os.listdir(file_path)
    print(f'返回指定目录【{file_path}】下的所有文件和目录名:{os.listdir(file_path)}')
    return paths


if __name__ == '__main__':
    path = 'D:\pythonExcel'
    try:
        fileName = listdir(path)
        file_path = os.path.join(path, fileName[0])
        # 打开已有文件
        wb = load_workbook(file_path)
        # 创建一个新的sheet
        newSheet = wb["NewSheet"]
        # 设置新sheet为活动sheet
        wb.active = newSheet
        # 输入等线 24号，加粗斜体，字体颜色红色。
        # 直接使用cell的font属性，将Font对象赋值给它
        # 声明样式
        bold_italic_24_font = Font(name='等线', size=24, italic=True, color=Color(rgb="FF0000"), bold=True)

        # 给单元格设置样式
        newSheet['A1'].font = bold_italic_24_font

        wb.save(file_path)

    except Exception as e:
        print(f"Exception : {e}")

2.2. 给第二行设置样式"宋体"、大小为16磅、斜体、红色颜色和粗体

    return paths


if __name__ == '__main__':
    path = 'D:\pythonExcel'
    try:
        fileName = listdir(path)
        file_path = os.path.join(path, fileName[0])
        # 打开已有文件
        wb = load_workbook(file_path)
        # 创建一个新的sheet
        newSheet = wb["NewSheet"]
        # 设置新sheet为活动sheet
        wb.active = newSheet
        # 输入等线 24号，加粗斜体，字体颜色红色。
        # 直接使用cell的font属性，将Font对象赋值给它
        # 声明样式
        bold_italic_16_font = Font(name='宋体', size=16, italic=True, color=Color(rgb="FF0000"), bold=True)

        # 给第二行设置样式
        for cell in newSheet[2]:
            cell.font = bold_italic_16_font

        wb.save(file_path)

    except Exception as e:
        print(f"Exception : {e}")

2.3. 给第三行数据设置垂直居中和水平居中

        for cell in newSheet[3]:
            cell.alignment = Alignment(horizontal='center', vertical='center')
        wb.save(file_path)
