句子结构分析,这是宾语从句吗?
it doesn't matter in what order the letters in a word are,the only important thing .其中in what order 是做什么成分呢

in what order the letters in a word are是状语。
in...........是状语。
in介词what....相当一个名词,介+名作状语

主语从句.the letters in a word are in what order是真正主语.it是形式主语.in what order在从句里做宾语,或者说是表语(表语,之前说错了).
