如何将包含大段落的表格放在跨两列的行中？

Question

我正在使用 IEEEtran 类编写一个 tex 文件。它将文本放在两列中。我有一个表格，我想将其放在两列中。几个单元格内的文本相当大。我希望页面看起来像这样：

请忽略文本下方的红线，因为我是在 MS Word 中准备此示例的。

我知道这个问题似乎很常见。我尝试了这些解决方案，但没有成功：双列模式的页面宽度表格，在两列样式页面中创建表格，如何将全宽表格放在与参考文本相同的双列页面的顶部或底部？

以下是我编写的代码：

\begin{table*}[t]

我没有遇到任何编译错误。我的表格超出了页面，如下所示：

Answer 1

为了使表格适合文本块，我建议您使用一个tabularx环境，X其中第二列和第三列具有（修改后的）列类型，p第四列具有（修改后的）列类型；这样，LaTeX 就可以在这些列中插入换行符（如果需要）。（这些\RaggedRight指令指示 LaTeX 以右对齐模式而不是完全对齐模式排版材料，同时仍允许连字符。）

\documentclass[]{IEEEtran}
\usepackage{tabularx,multirow,ragged2e}
\setlength\extrarowheight{2pt} % for a slightly more "open" look
\newcolumntype{Y}{>{\RaggedRight\arraybackslash}X}
\newcolumntype{P}[1]{>{\RaggedRight\arraybackslash}p{#1}}

\usepackage[colorlinks,allcolors=blue]{hyperref}
\begin{document}

\begin{table*}[t]
