无法勾勒出多列表格标题

我正在尝试制作一个包含四列的表格。标题是包含的特征、标准化、RMSE、数字。我当前的代码：

\begin{table}[htpb]
\caption{Tested models}
\begin{tabular}{cccc}
\toprule
Included features & \multicolumn{3}{c}{Normalization}{RMSE}{Number} \\
\midrule
Close, volume & None & 18153.33 & 1 \\
\midrule
Close, volume, rsi, sma, ema, $stoch_k$, $stoch_d$ & None & 24292.86 & 2 \\
\midrule
Close, volume, rsi, sma, ema, $stoch_k$, $stoch_d$ & L2 & 15596.44 & 3\\
\midrule
\shortstack{Close, volume, rsi, sma, ema, $stoch_k$, \\ $stoch_d$, ad, cci, macd} & L2 & 18290.07 & 4\\
\midrule
\shortstack{\textbf{Close, volume, quote av, trades, tb base av,} \\ \textbf{tb quote av, rsi, sma, ema, $stoch_k$, $stoch_d$}} & \textbf{L2} & \textbf{12835.51} & \textbf{5} \\
\midrule
\shortstack{Close, volume, quote av, trades, tb base a, \\ tb quote av, rsi, sma, ema} & L2 & 13390.82 & 6\\
\midrule
\shortstack{Close, volume, quote av, trades, tb base av, \\ tb quote av, rsi, sma, ema, $stoch_k$, $stoch_d$, ad, cci, macd} & L2 & 13042.53 & 7\\
\midrule
\shortstack{Close, volume, quote av, trades, tb base av, \\ tb quote av, rsi, sma, ema, $stoch_k$, $stoch_d$, ad, cci, macd} & None &  22602.08 & 8\\
\bottomrule
\end{tabular}
\bigskip
\end{table}

使用此代码，表格如下所示： 在此处输入图片描述

如您所见，Normalization、RMSE 和 Number 的轮廓很奇怪。我对 latex 的使用经验不多，所以不太清楚这是怎么回事。我是不是误解了 \multicolumn 的工作原理？

答案1

我不确定为什么multicolumn你的表格有 4 列，但multicolumn结果却变成了 1+3 列。你的代码（在article类中）生成的表格对于文本宽度来说太宽了。

在下面的 MWE 中，我已丢弃multicolumn4 个常规列。我注意到短语“收盘价，成交量”出现在第一列的每个条目中，因此我认为最好将其删除并记录在其他地方，以简化外观。

有些shortstack结果有点太宽，所以我对它们做了一些修改（缩短了一些行，增加了行数）。结果是一个适合文本宽度的表格。

我觉得有一种比使用更方便（自动？）的方法来获取多个输入行shortstack（我对您使用这种方法印象深刻）；希望其他人可以对此提出建议。在此处输入图片描述

答案2

由于“标准化”、“RMSE”和“数字”似乎是三个单独列的标题，因此只需替换\multicolumn{3}{c}{Normalization}{RMSE}{Number}即可Normalization & RMSE & Number获得预期的输出。

在以下 MWE 中，我还使用了该tabularx包，以便允许在第一列自动换行，同时确保表格适合文本宽度。第二个示例显示的表格行数较少，但有一些空白，并且第一列的对齐方式也不同。
