我有一张使用tabular环境的表：

运行良好，并出现在文档中我想要的位置，但是当我向表中添加一个或多个项目时，表会出现在文档底部的引用下方。这是为什么？另外，我不确定如何解析这里的乳胶代码来向您显示表格 - 如果有人能告诉我怎么做那就太好了。
答案1
解决浮动“浮动”到纸张背面的问题的最快方法可能是简单地省略h位置说明符。如果需要，请使用位置[t!]说明符。
为了很多有关 LaTeX 如何“决定”放置浮动元素的更多信息，请参阅帖子如何影响 LaTeX 中图形和表格等浮动环境的位置？尤其是 Frank Mittelbach 的详尽回答。
关于您的表格的一些补充说明：似乎指定的列数比必要的多得多。事实上，似乎只有两列。虽然如果您指定表格应该有大约 10 列，不会发生任何不好的事情，但指定的列越多，调试任务就会变得更加繁琐。顺便说一句，您可以将文本左对齐，而不是将每列的内容居中。并且，考虑使用环境tabularx并使用X第二列的列类型，以便让长条目根据需要换行。
