HTML table :New row

[wence]

'how to add a new row to existing table row..Im using <asp:table>..with the following code it tends to remove all the previous row then only add in a new row?

 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim m_text As String, m_row As TableRow, m_cell As TableCell, m_date As String, m_time As String
        m_text = TextBox1.Text
        m_date = "" : m_time = "" : getdatetime(m_date, m_time)
        'row one
        m_row = New TableRow
        'left cell
        m_cell = New TableCell
        m_cell.Width = 300
        m_cell.Text = "Date= " & m_date & " <br/>" & _
                     "Time= " & m_time & ""
        m_row.Cells.Add(m_cell)
        'right cell
        m_cell = New TableCell
        m_cell.Width = 700
        m_cell.Text = m_text
        m_row.Cells.Add(m_cell)
        table1.Rows.Add(m_row)

    End Sub

BTW when i type in something in a textbox, all the previous items entered in that textbox will be listed out, how to remove it?
