我在格式化表格时遇到问题。出于某种原因,colspans和rowspans不起作用,单元格被放入可用的第一行和第一列。我已经创建了列组,用于指定列的宽度。我的代码在这里:html表格格式行和列
<table class = “programs” border=“1”
summary=“Lists the morning programs aired by KPAF from 5:00 a.m. to 12:00p.m.(central time).>
<caption> All Times Central </caption>
<colgroup>
<col class = “timeColumn” />
<col class = “wDayColumns” span =“5”/>
<col class = “wEndColumns” span=“2”/>
</colgroup>
<thead>
<th>Time</th>
<th>Monday</th>
<th>Tuesday</th>
<th>Wednesday</th>
<th>Thursday</th>
<th>Friday</th>

请提供更多信息请问究竟出了什么问题?当我在[JSFiddle](http://jsfiddle.net/WW3bh/19603/)中运行你的代码时,似乎他们正在正确地计算出它们的宽度,但我并不完全理解你的问题。 – Aeolingamenfel 2014-09-28 22:18:00
