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。

比如

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)
    Next
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)
    Next
end if
Next

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。

参考：http://www.foxtable.com/webhelp/topics/0400.htm
Dim drs As List(of DataRow) = DataTables("表A").Select("学校=\'第一中学\'","成绩 desc")

请问如何把他们合并到一起？
