css:为什么这些表的宽度不一样?

时间:2010-08-16 23:00:39

标签: css

我认为在所有行上使用100%会使它们的大小相同,但我显然是错的。

a)如何解决这个问题,以便所有表格的宽度与最宽的表格相同?

b)如何为所有行设置固定宽度?

首先是第一件事:你有#layouttable个id的多个实例。这是无效的,您在给定页面上只能有id的一个实例。我建议将其转换为类名。

顺便提一下,你也没有有效地使用级联(或者,在我看来,正确),假设你正在为不同的行重复css声明,你可以修改为:

tr {border: 0; text-align: center; }

tr.row1 {background-color: #ccc; }
/* etc. */

如果然后为类layouttable的表定义宽度,则所有表的宽度都相同:

如何解决此问题,以便所有表格的宽度与最宽的表格相同?

将表格的宽度定义为100%,这样就可以展开以填充其父元素提供的水平空间。

  

如何为所有行设置固定宽度?

表行始终与其父表一样宽。除非我从xhtml / css到现在都错过了一些非常基本的东西。至少我从未成功(或故意)尝试为tr分配宽度,因为这种理解。

测试了以下内容:

table  {width: 100%; }
tr {width: 10%; }

使用Ubuntu 10.04上的Chrome 5.0.375.125中的html(上图),我的假设似乎有效:该行似乎完全忽略了width属性。

答案 1 :(得分:0)

将宽度设置为表而不是行。
