我在Django views.py中生成excel，但是由于列名有点长，我每次都很难手动设置自动列适合宽度我/用户下载了excel 。
下面是我使用xlswriter生成excel的工作代码段。
def excel(request):
ans = request.POST.getlist('ans[]')
ans_final=[]
rows = request.POST.get('rows')
for each_ele in ans:
each_ele = each_ele.split('.')
each_ele[0] = each_ele[0][:-2]
each_ele[1] = each_ele[1][:-2]
fin = each_ele[0]+' - '+each_ele[1]
ans_final.append(fin)
workbook = xlsxwriter.Workbook('/home/Desktop/status.xlsx')
worksheet = workbook.add_worksheet('Test_Data')
bold = workbook.add_format({'bold': True})
for i in range(len(ans_final)):
worksheet.write(0, i,ans_final[i],bold)
row_index=1
row_count = int(rows)
while(row_count):
col_index=0
for each_ele in ans:
worksheet.write(row_index, col_index, eval(each_ele))
col_index += 1
row_index += 1
row_count -= 1
workbook.close()
return JsonResponse({'ok':'ok'})
请在上面的代码中建议设置自动调整列宽的解决方法。
您可以尝试使用worksheet.set_column(<start_col>, <end_col>, <width>)功能吗？
或者，如果您希望它自动正确地自动适应，我认为您需要win32com库？
在将数据添加并保存到电子表格后，您必须运行类似的内容：
import win32com.client as win32_client
excel_application = win32_client.gencache.EnsureDispatch('Excel.Application')
workbook = excel_application.Workbooks.Open(`<path_to_file>`)
worksheet = workbook.Worksheets("Test_Data")
worksheet.Columns.AutoFit()
workbook.Save()
excel_application.Application.Quit()
[遗憾的是，无法为Excel文件格式的列指定“自动调整”。此功能仅在运行时从Excel内可用。通过在写入时跟踪列中数据的最大宽度，然后在末尾调整列宽，可以在应用程序中模拟“自动调整”。从文档中的FAQ。
您可以在向列内写入数据时更新代码并跟踪列数据长度。这将进入您的while循环内。
def excel(request):
ans = request.POST.getlist('ans[]')
ans_final=[]
rows = request.POST.get('rows')
for each_ele in ans:
each_ele = each_ele.split('.')
each_ele[0] = each_ele[0][:-2]
each_ele[1] = each_ele[1][:-2]
fin = each_ele[0]+' - '+each_ele[1]
ans_final.append(fin)
workbook = xlsxwriter.Workbook('/home/Desktop/status.xlsx')
worksheet = workbook.add_worksheet('Test_Data')
bold = workbook.add_format({'bold': True})
for i in range(len(ans_final)):
worksheet.write(0, i,ans_final[i],bold)
row_index=1
row_count = int(rows)
cell_width = {}
while(row_count):
col_index=0
for each_ele in ans:
cell = worksheet.cell(row_index, col_index)
cell.value = eval(each_ele)
if cell.column_letter in cell_width:
cell_width[cell.column_letter].append(len(eval(each_ele)))
else:
cell_width[cell.column_letter] = [len(cell_value[0])]
col_index += 1
row_index += 1
row_count -= 1
for key in cell_width.keys():
width = max(cell_width[key])
worksheet.column_dimensions[key].width = width + 5
workbook.close()
return JsonResponse({'ok':'ok'})
这里，我将每个值的长度保留在列表中，然后获取最大数量，然后将其设置为列宽。我要添加5，以在内容之后添加一些额外的空间。我希望这能帮到您。 :)
