表格垂直线溢出和文本宽度问题，我哪里错了？

Question

设置

我使用 以不同的方式分隔了 3 个段落tabular。以下是 ：

\documentclass[11pt]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{titlesec}
\usepackage{lipsum}

%heading
\setlength\parskip{0pt}

\titleformat{\section}
  {\scshape\Large\bfseries}{}{0em}{\vspace{2pt}}[\hrule height 1pt]
\titlespacing*{\section}
  {0pt}{0pt}{10pt} 


%leftbar
\usepackage{array, xcolor, lipsum, bibentry}
\definecolor{lightgray}{gray}{0.8}
\newcolumntype{L}{>{\raggedleft}p{0.10\textwidth}}
\newcolumntype{R}{p{0.86\textwidth}}
\newcommand\VRule{\color{lightgray}\vrule width 0.5pt}

$----------------------------------------------------------------------------
\begin{document} 

%Example 1
\section{Example of text width that is should be}
\lipsum[1]

%Example 2
\bigskip
\section{Example tabular with vRule}

\hspace{-27pt}
\begin{tabular}{L!{\VRule}R}
\textbf{name} - (date)\\&

\lipsum[1] \\
\end{tabular}

%Example 3
\bigskip
\section{Example tabular with textwidth}

\hspace{-11pt}  
\begin{tabular}{r|p{0.80\textwidth}}

\emph{name}&{\bf location}\\\textsc{date}\\&

\lipsum[1] 
\begin{itemize}
\item item 3
\item item 2 
\item item 1

\end{itemize}\\
\end{tabular} 



\end{document}  

问题（第二段和第三段）

如您所见，第一个问题是文本没有与页面宽度对齐，我过去常常用\hspace{}眼睛对齐左侧，但我无法对齐右侧。

第二个问题是文本下方有空白，并且垂直线超出了段落。

目标

我的格式哪里错了？如何让所有内容都像第一段一样放置在“统一”的图像中。

编辑：上面的代码有要包含的项目符号，但图像没有显示这一点

Answer 1

这是由于在计算第二列的宽度时采用了近似值，并且您没有考虑到单元格之间的一些填充（tabcolsep), in particular after the last column. You can have an exact calculation usingtabularx . Also, instead of adding a negative horizontal space before the table, approximately measured, just add\noindent . Last, the vertical line overflow is simply a side effect of using the\lipsum` 宏：插入真实文本时不会产生这种副作用。

以下是没有这些缺点的代码：

\documentclass[11pt]{article}
\usepackage[margin=0.5in, showframe]{geometry}
\usepackage{titlesec}
\usepackage{enumitem}
\usepackage{lipsum}

%heading
\setlength\parskip{0pt}

\titleformat{\section}
  {\scshape\Large\bfseries}{}{0em}{\vspace{2pt}}[\hrule height 1pt]
\titlespacing*{\section}
  {0pt}{0pt}{10pt}


%leftbar
\usepackage{tabularx, xcolor, lipsum, bigstrut}
\definecolor{lightgray}{gray}{0.8}
\newcolumntype{L}{>{\raggedleft}p{0.10\textwidth}}
\newcolumntype{R}{p{0.86\textwidth}}
\newcommand\VRule{\color{lightgray}\vrule width 0.5pt}

\begin{document}

%Example 1
\section{Example of text width that is should be}
\lipsum[1]

%Example 2
\bigskip
\section{Example tabular with vRule}

\noindent
\begin{tabularx}{\linewidth}{@{}L!{\VRule}X@{}}
\textbf{name} - (date)\\
& \lipsum[1]
\end{tabularx}

%Example 3
\bigskip
\section{Example tabular with textwidth}

\noindent
\begin{tabularx}{\linewidth}{@{}r|X@{}}
\emph{name}&{\bfseries location}\\\textsc{date}\\
