主题：[求助]这个问题怎么解决

            For i As Integer = 3 To tb.Rows.Count
               
                Dim text1 = tb.cell(i,2).Range.Text.trim(chr(13))
                If len(text1) =0 Then Continue For
                nr = Tables("学生").AddNew
                nr("学号") = text1.replace(chr(13),"") 
               
                text1 = tb.cell(i,3).Range.Text
                nr("姓名") = text1.replace(chr(3),"") 
               
                text1 = tb.cell(i,6).Range.Text
                nr("成绩") = text1.replace(chr(6),"")  

           Next
