-- [求助]如何实现年级排名与班级排名公式
学生成绩汇总表中有某某学科班级排名和某某学科年级，如：语文年级排名、语文班级排名、数学年级排名、数学班级排名等，下面这段：Tables("学生成绩汇总表").StopRedraw
Dim bjs As List(Of String) = DataTables("学生成绩汇总表").GetValues("班级","[班级] Is Not NULL")
Dim Count As Integer
Dim ColNames() As String = {"语文","数学","英语","化学","物理","总分"}
Dim TotalName As String
For Each ColName As String In ColNames \'
For i As Integer = 0 To bjs.Count -1
Dim drs As List(Of DataRow) = DataTables("学生成绩汇总表").Select("[班级] = " & bjs(i), ColName & " DESC")
Count = 0
TotalName = ColName & "排名"
For n As Integer = 0 To drs.Count - 1
Count = Count + 1
If n > 0 AndAlso drs(n)(ColName ) = drs(n-1)(ColName) Then
drs(n)(TotalName ) = drs(n-1)(TotalName )
Else
drs(n)(TotalName ) = Count
End If
Next
Next
Next
Tables("学生成绩汇总表").Sort = "总分 DESC"
Tables("学生成绩汇总表").ResumeRedraw

添加对应的语文年级排名、语文班级排名等等列，然后代码条件改为年级不就行了
Tables("学生成绩汇总表").StopRedraw
Dim bjs As List(Of String) = DataTables("学生成绩汇总表").GetValues("年级","[年级] Is Not NULL")
Dim Count As Integer
Dim ColNames() As String = {"语文","数学","英语","化学","物理","总分"}
Dim TotalName As String
For Each ColName As String In ColNames \'
For i As Integer = 0 To bjs.Count -1
Dim drs As List(Of DataRow) = DataTables("学生成绩汇总表").Select("[年级] = " & bjs(i), ColName & " DESC")
Count = 0
TotalName = ColName & "年级排名"
For n As Integer = 0 To drs.Count - 1
Count = Count + 1
If n > 0 AndAlso drs(n)(ColName ) = drs(n-1)(ColName) Then
drs(n)(TotalName ) = drs(n-1)(TotalName )
Else
drs(n)(TotalName ) = Count
End If
Next
Next
Next
Tables("学生成绩汇总表").Sort = "总分 DESC"
Tables("学生成绩汇总表").ResumeRedraw

如果要班级年级同时排名，先调用1楼的代码，再调用3楼的代码即可

老师，您给看一下这个附件：总是出现问题，按您说得，没有找到问题的原因。不知道问题出在哪里？

表达式的字符串需要使用单引号引起来：http://www.foxtable.com/webhelp/topics/1284.htm

谢谢老师！还有一个问题：学生成绩汇总表中的学科主观成绩，如语文主观、数学主观等，还有学科客观成绩 ，如语文客观、数学客观等，想引用主观题表中的成绩和客观题表中的成绩，主观题表中的成绩按学号，如何引用到学生成绩汇总表中，客观题的成绩如何按学号引用到学生成绩汇总表！
