删除表格上方的空间

Question

我创建了这样一个表格：

{\bf \color{LightBlue} \small repding} 
\begin{tcolorbox}[arc=0pt, outer arc=0pt ,colback=ColWhite, colframe = ColWhite]
        \begin{table}[H]
        \begin{tabularx}{\textwidth}{cX}
                     \textcolor{GrayMid}{Code} & \textcolor{GrayMid}{Description} \\ 
                    [0.3ex]
                    \hline
             \hyperref[fac68b5b180]{RA X} & RA\_O \\ \hline 
        \end{tabularx}
    \end{table}
\end{tcolorbox}

但是标题和表格之间出现了一条空行。有人能告诉我如何去掉它吗？

谢谢

例如，使用title={...}等选项并说。top=0pt

frame hidden大多数情况下都比 更好colframe=white，特别是当背景颜色不是白色时。

\documentclass{article}

\PassOptionsToPackage{x11names,dvipsnames,svgnames}{xcolor}
\usepackage[most]{tcolorbox}
\usepackage{tabularx}
\usepackage{hyperref}

\colorlet{ColWhite}{white}
\colorlet{GrayMid}{black!50}


\begin{document}
\begin{tcolorbox}[enhanced, sharp corners, frame hidden,colback=ColWhite,fonttitle={\bfseries\small}, coltitle={LightBlue}, title={repding},top=0pt]
  \begin{tabularx}{\textwidth}{cX}
    \textcolor{GrayMid}{Code} & \textcolor{GrayMid}{Description} \\ 
    [0.3ex]
    \hline
    \hyperref[fac68b5b180]{RA X} & RA\_O \\ \hline 
  \end{tabularx}
\end{tcolorbox}

\end{document}

使用 tabularx= 选项，可以在选项中直接使用，因此可以tcolorbox顺利地环绕tabularx环境。

\documentclass{article}

\PassOptionsToPackage{x11names,dvipsnames,svgnames,table}{xcolor}
\usepackage[most]{tcolorbox}
\usepackage{tabularx}
\usepackage{hyperref}

\colorlet{ColWhite}{white}
\colorlet{GrayMid}{black!50}


\begin{document}
\begin{tcolorbox}[enhanced, sharp corners,frame hidden,colback=ColWhite,fonttitle={\bfseries\small}, coltitle={LightBlue}, lefttitle={0pt}, title={repding},top=0pt, tabularx={cX}]
    \textcolor{GrayMid}{Code} & \textcolor{GrayMid}{Description} \\ 
    [0.3ex]
    \hline
    \hyperref[fac68b5b180]{RA X} & RA\_O \\ \hline 
\end{tcolorbox}

\end{document}
