最近有一个需求是对输出的excel格式进行处理，要求要美观，颜色要根据内容来显示不同规则
先上总代码：

上述代码思路:
1. 读取一个无格式的excel
2. 筛选出该excel内所有需要处理的excel表格
3. 针对每个excel 进行格式调整
4. 输出一个新的excel
PS： 需要安装xlsxwriter， to_excel engine选择该库
核心：定位到问题表格
workbook = writer.book，
worksheet1 = writer.sheets[sheet_name]
调整整列格式：worksheet1.set_column('A:T',10, fmt) fmt即为列的格式内容，字体，字体大小，横竖对齐等
fmt = workbook.add_format({"font_name": u"阿里巴巴普惠体","font_size":9,'valign': 'vcenter','align': 'center'})
for col_num, value in enumerate(df.columns.values):
worksheet1.write(0, col_num, value, fmt) #列名称写入
# 设置列宽以及格式
worksheet1.set_column('A:T',10, fmt)
worksheet1.set_column('A:A',8, fmt)
worksheet1.set_column('B:B',4, fmt)
worksheet1.set_column('C:C',7, fmt)
worksheet1.set_column('D:D',3, fmt)
worksheet1.set_column('E:E',2, fmt)
worksheet1.set_column('I:I',2, fmt)
worksheet1.set_column('H:H',6, fmt)
worksheet1.set_column('K:K',7, fmt)
worksheet1.set_column('L:L',6, fmt)
fmt = workbook.add_format({"font_name": u"阿里巴巴普惠体","font_size":9,'valign': 'vcenter','align': 'left'})
worksheet1.set_column('J:J',40, fmt)
worksheet1.set_column('P:P',30, fmt)
根据每列条件调整显示的格式：worksheet1.conditional_format, 同样的，选择区域后(如下代码为C列，L_END提前筛选了列长度)，对保护某一字段进行格式修改。修改为note_fmt
note_fmt = workbook.add_format({'bold':False,'font_name':u'阿里巴巴普惠体','font_color':'white','font_strikeout':False,
'align': 'center', 'valign': 'vcenter','underline':False,'bg_color':'#FF0000'})
worksheet1.conditional_format('C2:C%d' % l_end, {'type': 'text', 'criteria': 'containing', 'value': '原因分析', 'format': note_fmt})
同样的 criteria 除了containing也可以使用对比符号：
# worksheet1.merge_range('A1:B1', u'测试情况统计表', note_fmt)
# # 有条件设定表格格式：金额列
# worksheet1.conditional_format('B3:E%d' % l_end, {'type': 'cell', 'criteria': '>=', 'value': 1, 'format': amt_fmt})
# # 有条件设定表格格式：百分比
# worksheet1.conditional_format('E3:E%d' % l_end,
# {'type': 'cell', 'criteria': '<=', 'value': 0.1, 'format': percent_fmt})
# # 有条件设定表格格式：高亮百分比
# worksheet1.conditional_format('E3:E%d' % l_end,
# {'type': 'cell', 'criteria': '>', 'value': 0.1, 'format': highlight_fmt})
# # 加边框
# worksheet1.conditional_format('A1:E%d' % l_end, {'type': 'no_blanks', 'format': border_format})
# # 设置日期格式
# worksheet1.conditional_format('A3:A62', {'type': 'no_blanks', 'format': date_fmt})
操作完毕后进行保存即可
writer.save()
