openpyxl 列宽自动调整

openpyxl没有方便快捷的自动调整列宽的函数，只能自己写一个来实现。

from openpyxl.styles import Alignment
from openpyxl import Workbook

#计算单双字节
def realLenght(s:str):
    p = re.compile(r'[^\x00-\xff]+')    #t提取双字节字符
    doubleBytenum = len(''.join(p.findall(s)))
    singleBytenum = len(s)-doubleBytenum
    return doubleBytenum*2+singleBytenum;
#调整列宽
def autoFit(active_sheet:any)->None:
    for col in active_sheet.columns:
        max_lenght = 0
        column = col[1].column_letter   #避免合并单元格的问题
        for cell in col:
            try:
                l=realLenght(str(cell.value))
                if(l>max_lenght):
                    max_lenght = l
            except:
                pass
        auto_width = (max_lenght+2)*1.1
        active_sheet.column_dimensions[column].width=auto_width;
if __name__ == '__main__':
  #调整列宽
  autoFit(out_sheet)
  out_wk = Workbook()
  out_sheet=out_wk.active
  out_wk.save();
