这个公式如能身份证号专业学习形式这三项能加进去就完美解决，麻烦老师再修改一下，谢谢

这个是很简单的问题，请自行修改代码，看红色代码，修改其位置即可，如

     If sheet(i,0).text = "姓    名" Then
            Dim ndr As DataRow = dt1.AddNew
            ndr("学号") = sheet(i,5).text
            ndr("姓名") = sheet(i,1).text
            msgbox(sheet(i+1,5).Text)

msgbox(sheet(i+4,2).Text)

ndr("身份证") = sheet(i+1,5).Text
