如何从表中删除一列？

我有这张表： 在此处输入图片描述

最左边有一列标有索引。我想删除此列，但当我尝试时，表格将不再编译。任何帮助都将不胜感激！另外抱歉，我还不确定如何在这个网站上发布代码！

这是我的代码：

\begin{table}[H]

答案1

您没有提到您遇到了哪些错误，但删除第一列的信息应该很容易完成。

您不应使用数学模式将第二行标题中的单词设为斜体，\textit而应使用。单词内间距将得到极大改善。

另外，如下面第二个表格所示，您可能需要考虑通过删除所有垂直线和大部分水平线来整理表格，以及（对于剩余的水平线）获得比仅使用更好的间距：\hline该\booktabs软件包提供了命令\toprule、\midrule（\cmidrule带有修剪选项）和\bottomrule就是为了这个目的。最后，将数字与小数点符号对齐可能是一个好主意。

一些评论：

  1. 我会使用说明符h而不是H保留table“这里”，也就是说我会使用

    \begin{table}[h]

  2. 如果要强调某些文本，输入数学模式（如 ）{$Threshold$}并不是正确的方法。请使用\emph或\textit，例如\textit{Threshold}。
