如果我从热门的tutorialspoint.com网站复制一个表并将其粘贴到文本文件中，格式会受到严重干扰。例如，https://www.tutorialspoint.com/lua/lua_operating_system_facilities.htm处的表格如下：
Sr.No. Library / Method & Purpose
1
os.clock ()
Returns an approximation of the amount in seconds of CPU time used by the program.
2
os.date ([format [, time]])
Returns a string or a table containing date and time, formatted according to the given string format.
3
os.difftime (t2, t1)
Returns the number of seconds from time t1 to time t2. In POSIX, Windows, and some other systems, this value is exactly t2-t1.
4
os.execute ([command])
This function is equivalent to the ANSI C function system. It passes command to be executed by an operating system shell. Its first result is true if the command terminated successfully, or nil otherwise.
5
os.exit ([code [, close])
Calls the ANSI C function exit to terminate the host program. If code is true, the returned status is EXIT_SUCCESS; if code is false, the returned status is EXIT_FAILURE; if code is a number, the returned status is this number.
6
os.getenv (varname)
Returns the value of the process environment variable varname, or nil if the variable is not defined.
7
os.remove (filename)
Deletes the file (or empty directory, on POSIX systems) with the given name. If this function fails, it returns nil, plus a string describing the error and the error code.
8
os.rename (oldname, newname)
Renames file or directory named oldname to newname. If this function fails, it returns nil, plus a string describing the error and the error code.
9
os.setlocale (locale [, category])
Sets the current locale of the program. locale is a system-dependent string specifying a locale; category is an optional string describing which category to change: "all", "collate", "ctype", "monetary", "numeric", or "time"; the default category is "all". The function returns the name of the new locale, or nil if the request cannot be honored.
10
os.time ([table])
Returns the current time when called without arguments, or a time representing the date and time specified by the given table. This table must have fields year, month, and day, and may have fields hour (default is 12), min (default is 0), sec (default is 0), and isdst (default is nil). For a description of these fields, see the os.date function.
11
os.tmpname ()
Returns a string with a file name that can be used for a temporary file. The file must be explicitly opened before its use and explicitly removed when no longer needed.
如何在Vim中使用Regex重新格式化以便于阅读？我试过以下：
%s/\n\n/\t/g | %s/ \t\t/\t/g
但它让所有人都在一条线上。如何才能获得更好的显示效果，例如采用以下格式：
1<tab>function_name(arguements)
<tab>function description
2<tab>function_name(arguements)
<tab>function description
感谢您的帮助。
答案 0 :(得分：1)
这些替换似乎做得相当不错：
:%s/^\(\d\+\)\s*\n\n/\r\1\t
:%s/^\D/\t&
搜索部分：
^ anchor the search to the beginning of the line
\(\d\+\) capture group #1 consisting of 1 or more digits
\s* 0 or more whitespace characters
\n\n two newline characters
替换部分：
\r a newline character (\n in search, \r in replace)
\1 capture group #1
\t a tab character
搜索部分：
^ anchor the search to the beginning of the line
\D a non-digit character
替换部分：
\t a tab character
& the matched text
---编辑---
在整个缓冲区上执行这些替换的工作命令（并禁用hlsearch）：
:command! COMMANDNAME %s/^\(\d\+\)\s*\n\n/\r\1\t/ | %s/^\D/\t&/ | nohlsearch
请注意，替换的规范语法是：
s<separator>search<separator>replace<separator>[flags]
虽然可以在一次性命令中省略其中一些元素：
:s/foo/bar
:s/foo/
:s/foo
如果您想跟随另一个命令的替换，则必须使用最后一个分隔符。
适用于当前选择的变体（如果适用）或整个缓冲区：
:command! -range=% COMMANDNAME <line1>,<line2>s/^\(\d\+\)\s*\n\n/\r\1\t/ | '[,']s/^\D/\t&/ | nohlsearch
:help command-range和-range=% {/ 1}}见:help '[。
