抑制列條目和新定義的列分隔符號之間的空格

Question

正如另一篇文章中所解釋的，我定義了一個列分隔符，如下所示：

\newcolumntype{"}{@{\hskip\tabcolsep\vrule width 1pt\hskip\tabcolsep}}

使用普通的分隔符，|我通常@{}將列條目一個接一個地輸入。這不再起作用：有沒有辦法讓它也與新的分隔符號一起工作？

作為最小的完整工作範例，在第一個表中，文字Round與分隔符號間隔開，而在第二個表中，文字位於其旁邊：

\documentclass[a4paper,twoside]{article}

\usepackage{epsfig}
\usepackage{subfigure}
\usepackage{calc}
\usepackage{amssymb}
\usepackage{amstext}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{multicol}
\usepackage{pslatex}
\usepackage{apalike}
\usepackage{ulem}
\usepackage{tabularx}
\makeatletter
\newcommand{\thickhline}{%
    \noalign {\ifnum 0=`}\fi \hrule height 1.2pt
    \futurelet \reserved@a \@xhline
}
\newcolumntype{"}{@{\hskip\tabcolsep\vrule width 1pt\hskip\tabcolsep}}
\makeatother

Answer 1

使用

\newcolumntype{"}{!{\vrule width 1pt}}

不是

\newcolumntype{"}{@{\hskip\tabcolsep\vrule width 1pt\hskip\tabcolsep}}

!類似於@但不抑制自動\tabcolsep空格，因此相鄰的確實@{}會抑制它。
