主键列必须是自动递增的，才能用到高速合并功能。

否则，你就只能用写代码的方式合并 http://www.foxtable.com/help/topics/2334.htm

试试

Dim Book As New XLS.Book("c:\费用.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("凭证").StopRedraw()
'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
Dim nms() As String = {"ID,"摘要","借金额","贷方金额","科目代码"}
'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
For n As Integer = 1 To Sheet.Rows.Count -1
    Dim r As DataRow = DataTables("凭证").AddNew()
    For m As Integer = 0 To nms.Length - 1
        r(nms(m)) = Sheet(n,m).Value
    Next
Next
Tables("凭证").ResumeRedraw()
