阵列列之间的间隙

我在 tcolorbox 中使用数组，但数组的列之间出现了不必要的间隙。如何让此数组完美地适合父 tcolorbox 并消除列之间的间隙？

如果您确实想将表格放在 环境中tcolorbox，您可以尝试。该包提供了类似于经典的nicematrix环境，但使用 PGF/Tikz 为行着色（该环境应在此处与键 一起使用）。{NiceTabular*}{tabular}{NiceTabular*}colortbl-like

只是为了好玩，一个带有tcbraster（或tcbitemize）的解决方案。

\usepackage{xcolor}
\usepackage[most]{tcolorbox}
\usepackage{array}
\usepackage{colortbl}
\usepackage{lipsum}

\definecolor{darkgrey}{HTML}{E2E1E6}

%problembox environment
\newenvironment{problembox}
{%
    \renewcommand{\arraystretch}{1.5}
    \begin{tcbitemize}[
        colframe=white,
        colback=darkgrey,
        fontupper=\small\sffamily,
        sharp corners,
        raster columns=3,
        raster column skip=0pt,
        raster row skip=0pt,
        raster equal height=rows,
        raster row 1/.style={colback=black!30},
        halign=center,
        size=small,
        boxrule=0pt,
        ]}
{    \end{tcbitemize}
}

答案3

（在意识到我最初的答案关注的是与 OP 关心的不同类型的“差距”之后，我重写了这个答案。）

我如何使这个数组完美地适合父 tcolorbox 并消除列之间的间隙？

请注意

\begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}
    >{\centering\arraybackslash}p{\dimexpr0.33\textwidth}
    >{\centering\arraybackslash}p{\dimexpr0.33\textwidth}
    >{\centering\arraybackslash}p{\dimexpr0.33\textwidth}@{}}

三列的总宽度为0.99\textwidth为不是 1.00\textwidth。相反，两个列间间隙的宽度为0.005\textwidth，而不是0pt。要解决此问题，只需将上面显示的代码片段替换为

\begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}
    >{\centering\arraybackslash}p{\dimexpr0.333\textwidth}
    >{\centering\arraybackslash}p{\dimexpr0.333\textwidth}
    >{\centering\arraybackslash}p{\dimexpr0.334\textwidth}@{}}
