很多新手都是从案例开始对 TeX 感兴趣的，我就是其中之一
再进阶的时候，就是碰到了字体、宏包开发这些高级话题

TeX 3.141592653 (TeX Live 2023) pdfTeX 3.141592653-2.6-1.40.25 (TeX Live 2023) This is LuaTeX, Version 1.16.0 (TeX Live 2023) 环境设置也没有问题，overleaf 可以用，但是由于我文档太大了编译时间超过了免费版的时间，所以选择本地编译，也不应该这么难吧。。。
texhash && fmtutil-sys --all也试过了，没有用，包都是最新的。google 也搜不到相关资料，写一天论文 debug 半天也挺无力的。
安装后 5.6g ，30 万个文件，一个文字排版软件这么多文件就离谱，不知道多少无用的包都在里面，卸载都要十几分钟。
各种包相互冲突。为了实现一些常用的表格和公式，还要找一堆莫名其妙的包来实现，比如二重环路积分这种符号，结果各种包偶尔还会冲突。最后虽然写出了想要的效果，源码已经变成一坨屎了。
debug 困难，pdflatex - bibtex - pdflatex×2 四次编译下来根本不提示哪行出错了，只能写一点就编译一下。
感觉 latex 的使用体验早就和现在其他语言 /软件的体验脱节了，同时也看不到一点改进的可能。后悔当时没有点 word 排版科技树。

公式有 MathType ；加上 Toggle TeX 和接受 LaTeX 输入功能，勉强还可以接受。（插入公式时要呼出 MathType 窗口，用 Toggle TeX 又不是实时的，而且还不能转化$A$这种形式的公式）
至于形形色色的函数图象，几何图形，只能通过第三方软件+截图的办法处理了。
我想问的是，能否实现和 MathType 中 Toggle TeX 的功能，给出一段 metapost 代码，用 VBA 或者程序自动转化为 word 的插图。这个插图也像 mathtype 的公式一样可以修改。 是否有现成的实现这个功能的工具？如果没有，开发的思路是什么？谢谢！

问题在于表格不对齐， Google 试了几种方案都不行，求助。。。
还有什么要补充/建议的么？在这里谢谢各位V友了。。
]]>请教大家一个问题，出于速度的考虑，我把 MathJax 换成了 KaTeX 用来支持博客的 LaTeX 公式，但遇到个很囧的情况，有些比较常用的 TeX 符号， KaTeX 还是不支持的，比如微分算子 \nabla。
想请问下， V 站上有遇到相同问题的朋友们？你们是如何解决的？
谢谢诸位~
