我想把表学生名册里 1班的学生按照成绩前6名的学生提出来到表2， 1班剩下的学生放到表3； 2班的学生按照成绩前14名的学生提出来到表2， 2班剩下的学生放到表3. 请问如何实现能方便？

就是一个表分成两个表，按照成绩分出来。就是每班分出的人数不定。

Dim cj As Double

Dim drs As List(of DataRow) = DataTables("表A").Select("","成绩 desc")

For i As Integer = 0 To drs.count - 1

Dim dr1 As DataRow = drs(i)

If i < 6'前6名

Dim dr2 As DataRow = DataTables("表B").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

Else

Dim dr2 As DataRow = DataTables("表C").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

End If

这个代码挺好使，我想问一下，我再加个条件，如果“第一中学”的前6分出来， “第一中学”那个条件加在哪里啊。然后是“第二中学”“第三中学”“第四中学” 都按照固定的数分出来。谢谢。

Dim cj As Double

Dim drs As List(of DataRow) = DataTables("表A").Select("学校='第一中学'","成绩 desc")

For i As Integer = 0 To drs.count - 1

Dim dr1 As DataRow = drs(i)

If i < 2'前6名

Dim dr2 As DataRow = DataTables("表B").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

Else

Dim dr2 As DataRow = DataTables("表C").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

End If

Dim cj As Double

Dim drs As List(of DataRow) = DataTables("表A").Select("学校='第二中学'","成绩 desc")

For i As Integer = 0 To drs.count - 1

Dim dr1 As DataRow = drs(i)

If i < 3'前6名

Dim dr2 As DataRow = DataTables("表B").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

Else

Dim dr2 As DataRow = DataTables("表C").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

End If

Dim cj As Double

Dim drs As List(of DataRow) = DataTables("表A").Select("学校='第三中学'","成绩 desc")

For i As Integer = 0 To drs.count - 1

Dim dr1 As DataRow = drs(i)

If i < 2'前6名

Dim dr2 As DataRow = DataTables("表B").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

Else

Dim dr2 As DataRow = DataTables("表C").AddNew()

For Each dc As DataCol In DataTables("表A").DataCols

dr2(dc.Name) = dr1(dc.name)

End If

请问如何把他们合并到一起？

你好，我这个每个学校取的学生不一样，比如一中 2名，二中 3名，三中 4名，如何设置啊
