   Strl =" "
   For i = 1 To 9
      For j = 1 To 9
            If【  】Then
                  Strl =Strl +Str$ (j) +" x" +Str$ (i) +" =" +Str$ (Val(i*j))
            Else
                  Strl = Strl & Chr( 13 )
            【  】
            End If
      Next
   Next
   Print Strl

选项

答案j＜=i ,Exit for

解析本题考查了双重For循环和转换函数。Str $(x)：把x的值转换为一个字符串；Chr(x)：把x的值转换为相应的ASCII字符。
