下面是我用的代码参考一下，代码也是在各位老师的帮助下完成的
参考：有日期、年、月、日、季五列，日期为时间，年月日季为字符
For Each dr As DataRow In DataTables("公司信息").DataRows
Dim qs As Integer = dr("每月第一天")
Dim js As Integer = dr("每月最后一天")
If e.DataCol.Name = "日期" Then
If e.DataRow.IsNull("日期") Then
e.DataRow("年") = Nothing
e.DataRow("月") = Nothing
e.DataRow("季") = Nothing
e.DataRow("日") = Nothing
Else
Dim d As Date = e.NewValue
If d.Month = 12 And d.day >= qs Then
e.DataRow("年") = d.Year +1
Else
e.DataRow("年") = d.Year
End If
If d.Day < qs Then
e.DataRow("月") = d.Month
Else If d.Month = 11 Then
e.DataRow("月") = 12
Else
e.DataRow("月") = (d.Month + 1) Mod 12
End If
If d.day > js Then
e.DataRow("季") = DatePart("q",d.AddDays(10))
Else
e.DataRow("季") = DatePart("q",d)
End If
e.DataRow("日") = d.Day
End If
End If
next
DataRowAdding
e.DataRow("日期") = Date.today()
