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 )
