VB.Net的问题，输入整数n，显示具有n行的杨辉三角形。

VB.Net的问题，输入整数n，显示具有n行的杨辉三角形。

参考：
以下为十行的杨辉三角输出，根据这个自己做相应修改，都做好了，那你就是伸手党了。
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i, j As Integer

Dim dete(n, n) As Integer

dete(i, j) = 1
ElseIf j = 0 Then

ElseIf i = j Then
dete(i, j) = 1
Else
dete(i, j) = dete(i - 1, j - 1) + dete(i - 1, j)
End If

Next
For i = 0 To n
For j = 0 To i
Debug.Write(dete(i, j) & " ")
sum += dete(i, j)
Next
Debug.WriteLine(" ")
Next
End Sub
