第一个1有点问题啊
这个图形是上下对称的

Private Sub Command1_Click()
For i = 1 To 7 Step 2
s =
For j = 1 To 7 - i Step 2
s = s &
Next j
m =
For k = 1 To i
m = m & i
Next k
s = s & m
Print s
Next i
If i = 9 Then
For i = 5 To 1 Step -2
s =
For j = 7 - i To 1 Step -2
s = s &
Next j
m =
For k = i To 1 Step -1
m = m & i
Next k
s = s & m
Print s
Next i
End If
End Su
