1、合并数据

 

Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
    Dim t As Table = Tables("表B")
    t.StopRedraw()
    Dim Book As New XLS.Book(dlg.FileName)
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim r As DataRow = t.DataTable.Find("第一列 = '" & sheet(n, 0).text & "'")
        If r Is Nothing Then r = t.DataTable.AddNew()
        For i As Integer = 0 To sheet.Cols.Count -1
            Dim cname As String = sheet(0, i).text
            If t.Cols.Contains(cname) Then
                r(cname) = sheet(n, i).Text
            End If
        Next
    Next
    t.ResumeRedraw()
End If

 

 

2、如果要处理考试结果，可以在datacolchanged事件，写代码

 

If e.DataCol.name = "考试成绩" Then
    If e.NewValue >= 60 Then
        e.DataRow("考试结果") = "合计"
    Else
        e.DataRow("考试结果") = "不合计"
    End If
End If

参考2楼代码。不会做上传具体项目。

导入代码

 

Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
    Dim t As Table = Tables("学员考试信息")
    t.StopRedraw()
    Dim Book As New XLS.Book(dlg.FileName)
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim r As DataRow = t.DataTable.Find("身份证明号码 = '" & sheet(n, 2).text & "'")
        If r Is Nothing Then r = t.DataTable.AddNew()
        For i As Integer = 0 To sheet.Cols.Count -1
            Dim cname As String = sheet(0, i).text
            If t.Cols.Contains(cname) Then
                r(cname) = sheet(n, i).Text
            End If
        Next
    Next
    t.ResumeRedraw()
End If

 

DataColChanged事件

 

If e.DataCol.name = "考试成绩" Then
    If e.NewValue >= 60 Then
        e.DataRow("考试结果") = "合格"
    Else
        e.DataRow("考试结果") = "不合格"
    End If
End If
