Question

为什么第一列（ NUM ）和第二列（ DEPARTMENT ）中的表头与其他表头的其余部分不对齐？

HTML：

这是jsfiddle： https://jsfiddle.net/2xasogpq/

从jsfiddle中可以看到，没有涉及外部CSS。在chrome和firefox上，表格标题高度不均匀。请帮我。预先感谢。

Answer 1

均等

与CAPITAL PROPERTY相比，DEPARTMENT列的高度更高，因为为CAPITAL PROPERTY行创建了单独的tr标签。

Answer 2

原因是rowspan的值。由于 NUM 和 DEPARTMENT 列的值为3，这意味着它们将跨越三行。由于这是它们的大小，因此它们未对齐您的table。如果希望这些列成为第一行，只需将rowspan设置为1。

Answer 3

您的问题是单元格间距。您需要添加一些CSS来解决此问题。

table{
  border-collapse: collapse;
  border-spacing: 0;
}
td,th{
  border: 2px solid white;
}

提要：requireEnd
