尷尬的表格

Question

我需要建立一些尷尬的表格，如下所示。 到目前為止，我成功地在一定程度上（並不完美）創建了它們，如下所示。我確實需要一些幫助來產生更好的結果，如上面所示的原始結果。我的MWE如下圖所示，希望你們能幫忙。謝謝。

\usepackage{array}
\usepackage{amsmath}

\begin{document}
\begin{gather*}
        y = a_{0} +
        \begin{tabular}{|c|c|c|c|c}
                $b_{1}$                                            &
                $+\dfrac{1}{}$                                     &
                ------                                             &

Answer 1

我想你可以用\multirow這個。

在第一個陣列中，為了保持一致性，我將第一個加號放在第一個垂直規則之後。

\documentclass[a4paper,11pt,twoside]{book}

\usepackage{array}
\usepackage{multirow}
\newcommand{\myplus}{\multirow{2}{*}{$+$}}
\newcommand{\mymul}[1]{\multirow{2}{*}{$#1$}}
\begin{document}
\begin{gather*}
\begin{array}{l*4{|l>{$}p{1.5em}<{$}}|p{1.5em}}
     &&\mymul{b_{1}}&\myplus& 1 &&&&& \\
     \cline{5-10}
     &&&&&&\mymul{b_{3}}&\myplus& 1 & \\
     \cline{9-10}

\intertext{and}
