for i in range (1,7):
    sheet.cell(row=1,column=i).value = my_cellstatus_headders[i-1]
    sheet.cell(row=1,column=i).font = Font(bold=True)
    sheet.cell(row=1,column=i).fill = PatternFill(fgColor="D8D8D8", fill_type = "solid")
    sheet.cell(row=1,column=i).border = thin_border
    sheet.cell(row=1,column=i).alignment = alignment


columns = sheet.columns
#help (columns)
for col in columns:
    max_length = 0
    #print (col)
    for cell in col:
       try:
          if len(str(cell.value)) > max_length:
                max_length = int(len(cell.value))
       except:
            pass
       adjusted_width = max_length
       sheet.column_dimensions['col'].width = adjusted_width
try:
    mywb.save(log_path)
except:
    print ("Could not save the file ",log_path)

但是正在创建的 excel 工作表没有将列的宽度设置为单元格中的最大字符数。任何帮助或想法表示赞赏。

这能回答你的问题吗？ openpyxl - adjust column width size
嗨@APhillips，我对脚本很陌生，你能帮我修改上面的代码吗？或者您能否在您提供的链接中解释每行正确标记答案的重要性。再次感谢您的帮助。
能否请您从链接中解释正确答案：stackoverflow.com/questions/13197574/…
您没有在任何地方设置列宽。
嗨@CharlieClark，对，在我获得变量“adjusted_width”中的最大宽度后，如何将其设置为该特定列？

这对我有用，有什么办法让它变得更好吗？请建议。谢谢
