我的表格内部footnote似乎受限于第一个表格部分的宽度，我正在寻找一种方法来扩展它以占据整个表格的宽度。
我的文档采用样式格式two-column，我已使用环境table*将表格扩展到整个页面宽度。在此结构中，我将两个表格部分并排排列以形成两个不同的表格。此外，我还使用该threeparttable包来添加表格注释。
提供的代码生成下图中的输出。我想增强脚注以涵盖所有以红色突出显示的空白区域。

答案1
我建议您将两个较小的tabular环境都包裹在“外部”两列tabular环境中，并让“外部”表格环境跨越文本块的整个宽度。然后，确保threeparttable环境包裹这个“外部”表格环境。
我还将加载siunitx包并将其S列类型用于$\beta_0$两个内部tabular环境中的列，以对齐小数标记上的数字并获得正确的数学减号。
顺便说一句，没有必要粗体标题行中的单元格。
