我创建了一个表格 T，看起来很棒。我想创建另一个跨多页的表格，因此我添加了一个名为 ltablex 的包。结果发现，仅仅添加这个包就让表格 T 失去了格式。
代码如下。如果您注释掉 \usepackage{ltablex}，您会发现表格重新格式化 - 居中。查看添加 \usepackage{ltablex} 之后和之前的两个图片。请建议我使用哪个包来维护表格中的 X 功能，以及哪个包可以跨越多个页面。谢谢！

答案1
事实上，ltablex不起作用确切地例如tabularx：计算出的列大小X是最大限度此列的宽度，其实际宽度取决于其实际内容。如果您不想要它，请使用指令\keepXColumns。
但是，我宁愿加载 siunitx并使用S列类型，以便正确对齐小数点上的数值。我需要一些小技巧来使列标题居中，因为有些标题比数值所需的宽度要宽。
另外，我在第一个标题内插入了标题（就像长表格一样）。以下是结果，第一列为 类型X，没有指令：
