急！！！！
偶是刚学Vb,昨天偶在vB书中看到了如下例：（是一个小学乘法表的代码）
Private Sub Command1_Click()
Dim i As Integer, j As Integer
Dim expss As String
For i = 1 To 9
For j = 1 To i
expss = i & "×" & j & "=" & i * j
Picture1.Print Tab((j - 1) * 10 + 1); expss;
Next j
Picture1.Print
Next i
End Sub

Private Sub Picture1_Click()

End Sub
偶一直没有把 Picture1.Print Tab((j - 1) * 10 + 1); expss;这个表达式看懂，请哪位大侠指点一二.

Picture1.Print是在picture1里面打印
Tab((j - 1) * 10 + 1)是空格数据
expss 是表达i*j=结果
