我的问题类似这个问题，表格表和长表的标题对齐方式不同。我希望标题与表格形式一致，顶部边缘有一些白色填充，并与顶部规则的左侧对齐。我尝试按照建议使用 [singlelinecheck=off]，但它没有改变任何东西。然后我想尝试按照建议以另一种方式重新定义 \LT@caption，但我不知道如何重新定义它以使其成为表格形式。
我猜部分问题可能与我的预设边距有关，但即使我删除了 a4paper 设置，它也无法正确对齐。任何帮助或见解都将不胜感激。提前谢谢您！

除了使用该threeparttableex包之外，您还可以尝试该floatrow包及其 longtable 选项：LTcapwidth=content
