shell - vim 配置文件缩进问题

Question

不知道，怎地搞的，为什么在.vimrc文件里设置了:

set autoindent
set tabstop=2
set shiftwidth=2

死活按下「Tab」和「Shift」+「<」键，都是８个空格啊,还有就是按「o」进入编辑状态，也总是缩进８个空格....这是怎么回事。。。

Answer 1

Try adding a sentence

set cin

The questioner wrote the indentation setting in the conditional judgment statement, but it was not executed

Answer 2

set softtabstop=2
set expandtab
