Excel 宏vba 自动合并单元列

需求：

根据列合并； 同一列中相邻内容一致的合并成一个单元格， 以变美观

 

分析：

在须要合并的sheet中， 加入一个按钮， 点击此按钮

出现提示框， 让用户本身输入须要合并的列； 列名能够为数字或字母； 如输入1， 表明第一列； 输入A， 也表明第一列

自动判断全部的行数；

进行循环遍历； 将此列内容相同的相邻2列或几列， 合并单元格

难点:

合并单元格总出现提示框， 警告将丢失部分信息； 解决办法application.displayallert=false; 取消警告框；遍历完毕后， 再恢复displayalert=true
