为什么使用多列会改变我的表的其余部分？

Question

我目前正在使用 longtable 和 dcolumn 包创建一个 threeparttable，以便按“。”对齐我的数字。在我的标题下，我想写一个表格描述。我按照之前线程的建议尝试使用多列功能来解决该问题。但这不起作用，因为我的表格的其余部分突然移动了。有人对如何解决这个问题有什么建议吗？

我的代码：

\documentclass[
    fontsize=12pt, 
    twoside=off 
]{scrbook}

\usepackage{caption}
\usepackage[flushleft]{threeparttable}
\usepackage{longtable}
\usepackage{threeparttablex}
\usepackage{dcolumn}

\newcolumntype{C}[1]{>{\raggedright\arraybackslash}p{#1}}

\begin{document}
\begin{ThreePartTable}
\small
\renewcommand{\arraystretch}{0.75}
\begin{longtable}{@{\extracolsep{\fill}}ld{1.1}d{1.1}d{1.3}c}

\caption{Some very informative caption}
\label{Table:1} \\  

\multicolumn{5}{C{\textwidth}}{I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text. I am writing some text}\\

\toprule
\multicolumn{1}{@{\extracolsep{\fill}}l}{K} & \multicolumn{1}{c}{b} & \multicolumn{1}{c}{t} & \multicolumn{1}{c}{pval} & \multicolumn{1}{c}{R$^2$} \\


\toprule
\endfirsthead

\multicolumn{5}{@{\extracolsep{\fill}}l}{{\bfseries \tablename\ \thetable{} (continued)}}\\
\toprule
\multicolumn{1}{@{\extracolsep{\fill}}l}{K} & \multicolumn{1}{c}{b} & \multicolumn{1}{c}{t} & \multicolumn{1}{c}{pval} & \multicolumn{1}{c}{R$^2$} \\
\toprule   
\endhead

\midrule
\multicolumn{5}{r}{{Continued on next page}} \\
\midrule
\endfoot
\bottomrule
\endlastfoot

\multicolumn{5}{@{\extracolsep{\fill}}l}{Panel A: Hi}\\
\midrule
  10 & 0.10 & 0.10 & 0.100 & 0.00 \\ 
  10 & 0.10 & 0.10 & 0.100 & 0.00 \\ 
  10 & 0.10 & 0.10 & 0.100 & 0.00 \\ 
  10 & 0.10 & 0.10 & 0.100 & 0.00 \\ 
  10 & 0.10 & 0.10 & 0.100 & 0.00 \\ 
\end{longtable}
\end{ThreePartTable}
\end{document}

我希望我的表格看起来像这样：（没有多列文本的示例）

但不幸的是我得到了这个：

我尝试了多种方法，例如使用 xltabular 包而不是 longtable 包，指定不同的“p{}”，但似乎都不起作用。

解决方案如下tabularray：

\documentclass[
    fontsize=12pt, 
    twoside=off 
    ]{scrbook}

\usepackage{tabularray}
\UseTblrLibrary{siunitx}
\sisetup{group-digits=false}

\UseTblrLibrary{booktabs}
\NewColumnType{A}[1][1.2]{Q[si={table-format=#1},c,co=1]}

\DefTblrTemplate{conthead-text}{default}{(continued)}
\SetTblrStyle{caption-tag}{font=\bfseries}
