不需要，安装了texlive 之后，安装 WinEdt 自动就通过环境变量关联好了，如果是 11 版本自带了 pdf 阅读器，直接使用即可。

学会用 md 语法来输入代码。编辑器也有提醒。
我测试的代码正常，看看 multitoc 的说明：
\documentclass{ctexbook}
\usepackage{tabularray}
\usepackage[lot]{multitoc}
\begin{document}
\listoftables\let\cleardoublepage\clearpage
\NewTblrTheme{fancy}{
\SetTblrStyle{firsthead}{font=\bfseries}
\SetTblrStyle{firstfoot}{fg=blue2}
\SetTblrStyle{middlefoot}{\itshape}
\SetTblrStyle{caption-tag}{red2}
}
\begin{longtblr}[
theme = fancy,
caption = {A Table},
entry = {Caption},
]{
colspec = {XXX}
}
Head & Head & Head \\
\end{longtblr}
\end{document}
可以看看这个宏包 extarrows，但是箭头并没有分开，分开的话，可以自己定义了。
\documentclass[a4paper]{article}
\usepackage{amsmath}
\makeatletter
\newcommand*{\doublerightarrow}[2]{\mathrel{
\settowidth{\@tempdima}{$\scriptstyle#1$}
\settowidth{\@tempdimb}{$\scriptstyle#2$}
\ifdim\@tempdimb>\@tempdima \@tempdima=\@tempdimb\fi
\mathop{\vcenter{
\offinterlineskip\ialign{\hbox to\dimexpr\@tempdima+1em{##}\cr
\rightarrowfill\cr\noalign{\kern.5ex}
\rightarrowfill\cr}}}\limits^{\!#1}_{\!#2}}}
\newcommand*{\triplerightarrow}[1]{\mathrel{
\settowidth{\@tempdima}{$\scriptstyle#1$}
\mathop{\vcenter{
\offinterlineskip\ialign{\hbox to\dimexpr\@tempdima+1em{##}\cr
\rightarrowfill\cr\noalign{\kern.5ex}
\rightarrowfill\cr\noalign{\kern.5ex}
\rightarrowfill\cr}}}\limits^{\!#1}}}
\makeatother
\begin{document}
$A\doublerightarrow{a}{bcdefgh}B$
$A\triplerightarrow{d_0,d_1,d_2}B$
\end{document}

看不明白是啥意思？eqref？还是什么？
代码最好发出来。
网站已经很多例子了，封面的找找基本就知道了，基本就是背景图加上 TikZ 辅助，或者 tcolorbox 辅助。
要进行设置的，下面给个例子，代码来自这里：https://www.latexstudio.net/index/details/index/mid/755.html
\documentclass{beamer}
\mode<presentation> {

\usepackage{listings,color}

\begin{document}
\begin{frame}[fragile]
% \frametitle{用Lingo求解LP}
\begin{block}{Lingo代码}
\begin{lstlisting}
model:
max=50*x1+100*x2;

x2<=250;
x1>=0;
x2>=0;
end
\end{lstlisting}
\end{block}
\end{frame}
\end{document}
excel？还是 tikz？tikz 可以用 pgfplots 宏包：
\documentclass[border=3mm]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
title=Title,
width=7.8cm,
enlargelimits=0.15,
legend style={at={(0.5,-0.15)},
anchor=north,legend columns=-1},
ylabel={Pages},
bar width=7mm, y=4mm,
symbolic x coords={Firm 1, Firm 2, Firm 3, Firm 4, Firm 5},
xtick=data,
x tick label style={rotate=45,anchor=east},
nodes near coords align={vertical},
]
\addplot[ybar, nodes near coords, fill=black!10]
coordinates {(Firm 1,3) (Firm 2,7) (Firm 3,8) (Firm 4,13) (Firm 5,16)};
\addplot[draw=blue,ultra thick,smooth]
coordinates {(Firm 1,3) (Firm 2,7) (Firm 3,8) (Firm 4,13) (Firm 5,16)};
\end{axis}
\end{tikzpicture}
\end{document}
正确代码如下：
\documentclass{beamer}
\usepackage[export]{adjustbox}
\begin{document}
\begin{frame}[t]
\frametitle{Introduction}
\centering
{ \textbf{Quantum Information Processing}}
\begin{itemize}[<+->]
\item \includegraphics<1->[width=0.9cm,valign=c]{example-image-duck} University of Oxford
\item \includegraphics<2->[width=2.5cm,valign=c]{example-image-duck} Université de Montréal
\item \includegraphics<3->[width=2cm,valign=c]{example-image-duck} Université du Quebec
\end{itemize}
\end{frame}
\end{document}效果如下：
这种只能自己造轮子了。
看看下面的代码：
\documentclass[preview]{standalone}
\usepackage{unicode-math}
\usepackage{amsmath}
\makeatletter
\newcommand{\simedot}{\mathbin{\mathpalette\simedot@\relax}}
\newcommand{\simedot@}[2]{%
\ooalign{$\m@th#1\simeq$\cr\hidewidth\raise-.1em\hbox{$\m@th#1.$}\hidewidth\cr}%
}
\makeatother
\begin{document}
\[A \simedot B\]
\end{document}
代码是怎么写的？
可以尝试其他的公式字体，中英文比较协调的字体，我觉得还是 TeX Gyre Pagella 比如：
