Dynamically adding table rows to a asp.net table.

HI guys,
I'm trying to add new rows with cells that have text boxes in them. What I want is to have a table that the user enter's numbers into the text boxes think clicks on the button. A new rows appears so that they can add another ticker. But this is what I'm getting. when i add one row of data I click the button and a new row appears but the data shows up on the first row. They need to stay on each row. I'm not saving the data anyway. I do have viewstate to keep track of the rows but not sure what I'm doing wrong.

Code:

    <asp:Table ID="Table1" runat="server" Caption="Portfolio" Width="1001px">
        <asp:TableRow runat="server">
            <asp:TableCell runat="server">Ticker</asp:TableCell>
            <asp:TableCell runat="server"># Shares</asp:TableCell>
            <asp:TableCell runat="server">Price</asp:TableCell>
            <asp:TableCell runat="server">Buy Date</asp:TableCell>
            <asp:TableCell runat="server">Sell Date</asp:TableCell>
            <asp:TableCell runat="server">$ Gain</asp:TableCell>
            <asp:TableCell runat="server">% Gain</asp:TableCell>
        </asp:TableRow>
        <asp:TableRow runat="server">
            <asp:TableCell runat="server">
                <asp:TextBox ID="j0i0" runat="server"></asp:TextBox></asp:TableCell>
            <asp:TableCell runat="server"><asp:TextBox ID="j0i1" runat="server"></asp:TextBox></asp:TableCell>
            <asp:TableCell runat="server"><asp:TextBox ID="j0i2" runat="server"></asp:TextBox></asp:TableCell>
            <asp:TableCell runat="server"><asp:TextBox ID="j0i3" runat="server"></asp:TextBox></asp:TableCell>
            <asp:TableCell runat="server"><asp:TextBox ID="j0i4" runat="server"></asp:TextBox></asp:TableCell>
        </asp:TableRow>
    </asp:Table>

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        numrows = CType(ViewState("nums"), Integer) + 1
        addrows(numrows)
        ViewState("nums") = numrows
    End Sub

    Sub addrows(ByVal rows As Integer)
        Dim j As Integer = rows + 1
        For j = 0 To rows - 1 Step 1
            Dim arow As New TableRow
            For i = 0 To 4 Step 1
                Dim tb As New TextBox
                Dim tc As New TableCell
                tb.ID = "j" & j & "i" & i
                tc.Controls.Add(tb)
                arow.Cells.Add(tc)
            Next
            Table1.Rows.Add(arow)
        Next
    End Sub
