python电子表格样式修改20210208

需求描述:

共有多个业务部门，报表都放在 “各部门利润表汇总” 的文件夹下，需要把这些报表的格式统一。

报表原样式:

报表目的样式:

格式变化分析:

1.列宽:原表格列宽相同，而目的表格列宽个有不同；
2.颜色:目的表格包含三个颜色，分别对应第一行、最后一行还有中间几行的单元格；
3.边框:目的表格增加了边框下滑线；
4.对齐方式:新表格对齐方式采用居中。

小结

1.调整列宽用到的语句是Sheet.column_dimensions[‘列位置’].width = 列宽
如: ws.column_dimensions[‘A’].width = 10
2.单元格样式包括填充颜色fill、边框border、对齐方式alignment，分别是PatternFill、Border、 Side(‘thin’)对象
fill = PatternFill(‘solid’, fgColor=‘FF7F24’)
alignment = Alignment(horizontal=‘center’, vertical=‘center’)
border = Border(bottom= Side(‘thin’), right= Side(‘thin’))
