“那又怎样？”的意思，很无所谓，很不屑的一种表达方式。
1 so that
引导目的状语从句时，表示“以便；为了”，从句中常使用can /could /may /might /will /would /should等情态动词或助动词；引导结果状语从句时，从句中一般不用can和may等词，在so that前可以用逗号，意思是“因此;所以”。如：the little boy saved every coin so that he could buy his mother a present on mother's day.
2 so ... that ..
so＋形容词或副词＋that ...引导结果状语从句。意思是“如此……以致于……”。如：when the football fans saw beckham, they got so excited that they cried out.
大概意思：那有怎么样？
