我的桌子之间有很多不必要的空间

Question

我是制作表格的新手，我对表格之间的空间感到困扰。

这是我的代码，但是当我编译时，表格之间有一个很大的空白：

我究竟做错了什么？

Answer 1

@David Carlisle 说，您的桌子的定位是符合预期的。

如果您在第二个表格后添加一些文本，并更改​​页面上文本和浮动元素之间的空间比例，则两个浮动元素都将被推到页面顶部。例如：

\documentclass{article}
%--------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}

tabularrray如您所见，我使用包代替了导致表格从文本块右侧边框突出的表格代码，X[l]作为第二列表格。这样也简化了行的着色。

由于表格出现的上下文未知（它们是单独的吗？），您可以使用float包并只编写这两个表格，如下所示：
