为什么下面的代码只能复制一条选中行的数据
With Tables("员工工资表")
Dim n As Integer = .BottomPosition -.TopPosition
Dim m As Integer = n+1
Dim dr As Row = Tables("考勤表").AddNew(m)
For i As Integer = .TopPosition To .BottomPosition
dr("姓名") = Tables("员工工资表").Rows(i)("姓名")
Next
End With

搞定
Dim str As String = ""
For i As Integer = Tables("员工工资表").TopPosition To Tables("员工工资表").BottomPosition
str = str & "," & Tables("员工工资表").Rows(i)("_Identify")
Next
Dim f As New Filler
f.SourceTable = DataTables("员工工资表") \'指定数据来源
f.SourceCols = "姓名,工天" \'指定数据来源列
f.DataTable = DataTables("考勤表") \'指定数据接收表
f.DataCols = "姓名,合计" \'指定数据接收列
f.Filter = "[_Identify] in (" & str.Trim(",") & ")"
f.Fill() \'填充数据

还是这样好点
Dim str As String = ""
Dim Filter As String
For i As Integer = Tables("员工工资表").TopPosition To Tables("员工工资表").BottomPosition
str = str & "," & Tables("员工工资表").Rows(i)("_Identify")
Next
Dim Cols1() As String = {"姓名","工天"}
Dim Cols2() As String = {"姓名","合计"}
filter = "_Identify in (" & str.Trim(",") & ")"
For Each dr1 As DataRow In DataTables("员工工资表").Select(Filter)
Dim dr2 As DataRow = DataTables("考勤表").AddNew
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))

Next
