我是 LaTeX 新手，在格式化表格时遇到了问题。我想在表格下方添加一个长脚注，当它到达表格最后一列的边框时，立即开始新的一行。但是，当我添加脚注时，表格的最后一列会延伸到脚注所到之处。有谁能帮我吗？
这是我的完整代码：

答案1
环境threeparttable识别三个正式组件：标题、tabular（或tabular*、tabularx、tabulary）环境和tablenotes环境。threeparttable机器将标题和tablesnotes材料的宽度限制为tabular环境的宽度。因此，我建议您将当前位于环境底部的三行移到tabular新tablenotes环境中。
我还想建议您将 5 个数据列中的数字与各自的小数点对齐。这可以借助该dcolumn软件包来实现。请参阅下面的应用程序。
考虑到文本块的大小，\addlinespace每行后面都添加说明会使文本table太高。我建议您\addlinespace只在每四行后面插入说明。
哦，一定要把这些东西处理掉adjustbox。将表格材料adjustbox虚拟地放置在环境中担保表格中的字体大小与文档其余部分的字体大小将有很大的不一致。
