f[\[Delta] == 100;
For[t = 0, t <= 1, t = t + 0.2,
For[\[Alpha] = 0, \[Alpha] <= 180, \[Alpha] = \[Alpha] + 30,
For[\[Beta] = 0, \[Beta] <= 180, \[Beta] = \[Beta] + 60,
Print[N[R[\[Alpha], \[Beta]]]]]]]
Print["t:" t, " \[Alpha]:" \[Alpha], " \[Beta]:" \[Beta]],
None]

几个条件并列的话用Switch，嵌套的话就if里再写if。

我求求你们用Table好吗：https://tieba.baidu.com/p/5104865347
