列删除

1. 光标定位到要操作的地方。
2. CTRL+v 进入“可视 块”模式，选取这一列操作多少行。
3. d 删除。

列插入

插入操作的话稍有区别。例如我们在每一行前都插入”() “：

1. 光标定位到要操作的地方。
2. CTRL+v 进入“可视 块”模式，选取这一列操作多少行。
3. SHIFT+i(I) 输入要插入的内容。
4. ESC 按两次，会在每行的选定的区域出现插入的内容。

列替换

方法一：

1. ctrl + v ，切换到块操作模式。
2. 使用j. l等键进行上下左右操作，选中要替换的列。
3. 选中之后，按下 c 键，输入要替换的内容。这个时候会看到只有第一行被键入。
4. 按下 esc 键，退出块操作模式，这时所有列的字符都会被替换。

方法二：
选区，在 Visual 模式下选择区域后输入 : Vim 即可自动补全为 :'<,'>。

:'<,'>s/foo/bar/g
