大家好啊,我是阿宽,很高兴我们又见面了,整理一下最近群里的问题,希望对大家有所帮助哦~~ 请教一个事情,就是我一个excel的下拉框,怎么实现一次选择多个选项
Excel表格下拉框可以用数据验证/有效性实现,这里不好实现一次选择多个选项 。
接着输入字段名称,可以删除或添加选项,来调整选项的数量,再输入所有选项具体内容。现在AI这么发达,利用AI写宏代码,也可以实现这个功能。
打开DeepSeek输入提示词:
帮我写一段Excel VBA代码,实现在A2:A100单元格,下拉框一次可以多选:阿宽、王德宽、阿宽办公
一会DeepSeek就帮我生成好了代码,测试之后有点小问题,再把错误信息发给AI帮我修改了一版,再次运行后完美解决。最终效果如下:
下面把最终代码粘贴一份:
