我对你的设计感到疑惑，不知道你为什么不把描述放在标题里。我之前tabularray完成了表格的布局，并做了一些美化。不知道是否符合你的期望。

This table reports summary statistics of the analytical sample during the period from 2012 to 2014. Panel A shows heavy Internet user status based on people's Internet usage. Panel B shows individual characteristics. Panel C shows the summary statistics of residential LTE broadband availability.\\

答案3
我不确定我是否理解了你的格式目标，即。
我想让标题一直到表格的左侧，但保持整个表格居中
threeparttable我将这个目标解释为需要 (a) 一个环境来包含\caption指令和tabular环境，以及 (b) 一个\captionsetup带有选项justification=raggedright和的指令的组合singlelinecheck=false。
我忍不住发现\multicolumn{1}{l}{...}这三个字幕的包装器是多余的。要么完全省略这些包装器，要么用\multicolumn{6}{l}{...}包装器替换它们——就像我在下面的代码中所做的那样。
以下截图边缘的框线是因为这个showframe包是为这个测试文档加载的。你不需要在实际文档中加载这个包。

答案4
- 使用
tabularray包，其中标题格式留给caption包处理。 - 使用的是
talltblr表，tabularray相当于的threeparttable。
编辑：
- 对于面板标题，定义了新的命令（由
\NewTableComman），它收集此行的设置：\setCell[c=6]{...}，字体形状和字体。 - 由于 \SetCell 不允许（据我所知）使用
@{}面板标题文本的缩进（挂起）来更改单元格列分隔，因此\panel引入命令`\SetRow{...} 用于在标题上方添加空间（需要时）并将行内容向左移动：
