起因：做了个工具在console窗口罗列一些信息，基本结构是 [ 文件名        ：行号 ]，因为文件，行号长度不一，想要做到如下效果。

初步尝试，用以下方法：

string format = "{0,-10} {1,5}";  // -10 表示左对齐，10个字符宽；5 表示右对齐，5个字符宽
Debug.Log(string.Format(format, "File", "Line"));
Debug.Log(string.Format(format, "UI/Titan/UI_Titan_Main", "1"));
Debug.Log(string.Format(format, "Utils/GlobalFunction", "8"));

实际效果如下：

竟然没对齐？拷贝到IntelliJ 里查看

Utils/GlobalFunction                              |        :8
Lua/HookReloadLuaFuc                              |       :35
Lua/HookReloadLuaFuc                              |     :1290

IntelliJ用了等宽字符，所以看起来是对齐的。

后续就简单了，拿到console里字体的宽度就行了。

这里贴一个大概的实现，宽度表放在最后

一个简单的lua实现

local _QuickJumpTab = {
    "Utils/GlobalFunction:8",
    "Lua/HookReloadLuaFuc:35:print_table",
    "Lua/HookReloadLuaFuc:1290:print_table",
    "UI/Titan/TitanUtil:10:泰坦相关Gid",
}

local function GetFileLine(str)
    local strTab = split(str,":")
    return unpack(strTab)
end

-- 判断是否是中文字符 并且返回字符长度
local function IsChineseChar(char)
    local byte = string.byte(char)
    if byte >= 0x80 then
        return true,2
    else
        return false,1
    end
end

local function Utf8StringLen(str)
    local len = 0
    local strTab = StringToUtf8Table(str)
    for i, v in ipairs(strTab) do
        if IsChineseChar(v) then
            len = len + 12
        else
            len = len + _ConsoleCharWidth[v] or 3 -- 3 is width of space
        end
    end
    return len
end

local longestStr = ""
for k, v in pairs(_QuickJumpTab) do
    local fileStr = GetFileLine(v)
    if Utf8StringLen(fileStr) > Utf8StringLen(longestStr) then
        longestStr = fileStr
    end
end
local longestStrLen = Utf8StringLen(longestStr)
--logGreen("longestStrLen\t" .. longestStrLen)

local _wrapColor = function(color,str)
    return concat({"<color=",color,">",str,"</color>"})
end

-- 自己实现一个往左边或者右边加空格补齐长度的函数
-- 用于打印的时候对齐
local FillLen = function(str,len,align,fillStr)
    align = align or "left"
    local strLen = Utf8StringLen(str)
    if strLen >= len then
        return str
    end
    local spaceLen = len - strLen
    local needFillCount = max(spaceLen,1)
    if not fillStr then
        fillStr = " "
        needFillCount = needFillCount/_ConsoleCharWidth[fillStr]
    end
    local spaceStr = string.rep(fillStr,ceil(needFillCount))
    if align == "right" then
        return concat({str,spaceStr})
    else
        return concat({spaceStr,str})
    end
end

local exSymbolLen = _ConsoleCharWidth[":"] + _ConsoleCharWidth["["] + _ConsoleCharWidth["]"]

local _WrapDebugStr = function(file,line,des,fileColor,lineColor)
    fileColor = fileColor or "#CA550C"
    --"cyan"
    lineColor = lineColor or "#00FFFF"
    local maxFileLen = longestStrLen+8
    local fileStr = FillLen(file,maxFileLen,"right")
    local lineStr = FillLen(":" .. line,36,"left")
    fileStr = _wrapColor(fileColor,fileStr)
    lineStr = _wrapColor(lineColor,lineStr)
    local desFillStr = "-"
    local fillCharWidth = _ConsoleCharWidth[desFillStr]
    maxFileLen = maxFileLen + 36 + exSymbolLen
    if des then
        local colorLen = Utf8StringLen("<color=white></color>")
        des = _wrapColor("white",des)
        des = FillLen(des,(maxFileLen+colorLen)/fillCharWidth,"right",desFillStr)
    else
        des = FillLen("",maxFileLen/fillCharWidth,"left",desFillStr)
    end
    str = format("[%s%s]\n%s",fileStr,lineStr,des)
    return str
end
