Question

I would like to draw a table with 2 columns. The first column will have 2 rows each one containing a and b letters respectively and the second column containing no rows. here is my code.

Public Class trialtable
    Inherits System.Web.UI.Page

    Protected Sub trialtable(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim trial As DataTable
        trial = New DataTable
        Dim tbl As New Table()

        Dim szName As String = ""
        Dim szNumber As String = ""
        Dim szsadasd As String = ""
        tbl.BorderColor = Drawing.Color.Black
        tbl.BorderWidth = 1
        tbl.CellPadding = 0
        tbl.CellSpacing = 0

        For i As Integer = 0 To 1
            Dim tr As New TableRow()
            Dim tc1 As New TableCell()
            Dim tc2 As New TableCell()
            Dim tc3 As New TableCell()
            tc1.Controls.Add(New LiteralControl(szName))
            tc2.Controls.Add(New LiteralControl(szNumber))
            tc3.Controls.Add(New LiteralControl(szsadasd))
            tc1.BorderColor = Drawing.Color.Black
            tc1.BorderWidth = 1
            tc2.BorderColor = Drawing.Color.Black
            tc2.BorderWidth = 1
            tc3.BorderColor = Drawing.Color.Black
            tc3.BorderWidth = 1
            tr.Cells.Add(tc1)
            tr.Cells.Add(tc2)
            tr.Cells.Add(tc3)
            tbl.Controls.Add(tr)
        Next
        Me.Controls.Add(tbl)
    End Sub
End Class

Answer 1

In order to place the value a in the first cell of the first row, and b in the first cell of the 2nd row, and have nothing in the 2nd cell of both rows, replace the following lines of code...

tc1.Controls.Add(New LiteralControl(szName))
tc2.Controls.Add(New LiteralControl(szNumber))

With the following code...

If i = 0 Then
    tc1.Controls.Add(New LiteralControl("a"))
Else
    tc1.Controls.Add(New LiteralControl("b"))
End If
tc2.Controls.Add(New LiteralControl(" "))
