表格在顶部添加一个长列，并且 \multicolumn 已过时；请改用 \SetCell

Question

我正在尝试在工作中添加一个表格。我在上面画了一个带红色边框的矩形，以显示我想要放置长列的位置。然后，我得到了这些错误，如果我解决它们，表格渲染就会变得一团糟。

我的代码：

{\renewcommand{\arraystretch}{1.6}%
    \small
    \begin{table}[H]
        \small
        \centering
        \caption{}\label{tab:blockchains}
        \scalebox{0.97}{
            \begin{tblr}{colspec={l *{5}{X[c,m]}},
                    rows = {font=\linespread{1}\selectfont},
                    row{1} = {},
                    hline{1} = {2-7}{solid},
                    hline{2-7} = {solid},
                    vline{1} = {2-7}{solid},
                    vline{2-7} = {solid}
                }
                \SetCell[c=1]{c,white}
                \multicolumn{1}{l|}{} & Platform & Memory & Specification & Price \\
                \multicolumn{1}{|l|}{} & Windows & 16GB & Whatever & 10K \\
                \multicolumn{1}{|l|}{} & Windows, 32GB & Professional & 22K \\
                \multicolumn{1}{|l|}{} & Linux, 64GB & Hacker IBM & 32K \\
        \end{tblr}}
\end{table}}

Answer 1

这些冒犯\multicolumn看起来是没有必要的，只需将其删除：

\documentclass{article}

\usepackage{tabularray}
\usepackage{xcolor}


\begin{document}


  \begin{tblr}{colspec={l *{4}{X[c,m]}},
          hline{1-2} = {2-Z}{solid,red},
          hline{3-Z} = {solid},
          vline{1} = {3-Z}{solid},
          vline{2-Z} = {solid},
          vline{2-Z} = {1}{solid,red},
      }
      & \SetCell[c=4]{}\\ 
      & Platform & Memory & Specification & Price \\
      & Windows & 16GB & Whatever & 10K \\
      & Windows, 32GB & Professional & 22K \\
      & Linux, 64GB & Hacker IBM & 32K \\
\end{tblr}

\end{document}
