对excel表格数据添加样式

1.首先将数据写入到excel

import csv

import xlwt

def write_data_to_excel(unique_data_list):
    """unique_data_list:[{},{},{}]"""
    header_list = []
    for heades in list(unique_data_list[0].keys()):
        header_list.append(heades)

    with open('test.csv','a',newline='',encoding='utf-8') as f:
        writer = csv.DictWriter(f, fieldnames=header_list)
        writer.writeheader()
        for temp_dict in unique_data_list:
            temp_list = []
            temp_list.append(temp_dict)
            # writer.writerows(unique_data_list)
            writer.writerows(temp_list)

2.创建excel各种样式

#1 创建单元格背景颜色样式（颜色可自行查阅对应的数字编号，下面字体同理）

def create_bg_style():
    #创建一个样式对象，初始化样式 style
    style = xlwt.XFStyle()
    #设置背景颜色
    pattern = xlwt.Pattern()
    pattern.pattern = xlwt.Pattern.SOLID_PATTERN
    pattern.pattern_fore_colour = 4
    style.pattern = pattern # 将背景颜色加到表格样式中
    return style

#2 设置字体样式

def create_font_style():
    """设置字体样式"""
    style = xlwt.XFStyle()
    font = xlwt.Font()
    font.name = 'Calibri' #设置字体
    font.colour_index = 4 #设置字体颜色
    font.height = 400 #字体大小
    font.bold = True #字体是否为粗体
    font.italic = True #字体是否为斜体
    font.underline = True #字体是否有下滑线
    style.font = font
    return style

 

 

#3 设置水平位置

def set_position():
    """设置位置"""
    style = xlwt.XFStyle()
    alignment = xlwt.Alignment()
    alignment.horz = 1 #设置水平位置，0是左对齐，1是居中，2是右对齐
    #设置自动换行
    alignment.wrap = 1
    style.alignment = alignment

 

 

#4 设置边框

def set_border():
    """设置边框"""
    style = xlwt.XFStyle()
    borders = xlwt.Borders()
    #DASHED虚线， NO_LINE没有，THIN实线
    borders.left = xlwt.Borders.DASHED
    borders.right = xlwt.Borders.DASHED
    borders.top = xlwt.Borders.DASHED
    borders.bottom = xlwt.Borders.DASHED

    borders.left_colour = 1
    borders.right_colour = 1
    borders.top_colour = 1
    borders.bottom_colour = 1
    style.borders = borders
