我不确定这是否正是您正在寻找的内容，但您可以为每列中的所有内容提供相同的ID。例如：
<thead>
<tr>
<th></th>
<th scope="col" abbr="Starter" id="1" class="hovercss">Starter $250</th>
<th scope="col" abbr="Deluxe" id="2" class="hovercss">Basic $500</th>
<th scope="col" abbr="Medium" id ="3" class="hovercss">Medium $750</th>
<th scope="col" abbr="Business" id="4" class="hovercss">Business $1000</th>
<th scope="col" abbr="Platinum" id="5" class="hovercss">Platinum $1250</th>
</tr>
</thead>
确保＆＃34; Starter＆＃34;在表中也有id为1，依此类推。然后，您可以在onClick（）方法中执行类似的操作，这需要一些JavaScript：
document.getElementById("1").className = "hightlightPackage";
OR
document.getElementById("1").classList.add("highlightPackage");
为完成目的，该类将类似于：
.highlightPackage {
//what you want the column to look like when clicked
}
所以现在你要改变id = 1的所有东西的样式，这应该是整个列。一旦点击了不同的列，您可能还需要处理删除类。

我不确定我是否理解你的需要，但我有一个建议，你可以在这里看到它：https://codepen.io/FaridNaderi/pen/rwooxr
注意：请点击列标题。
// main click event handler
$('th').on('click',function(){
var th = $(this);
columnHighlight.css({
left: th.offset().left - 6, // 5 is padding-left of each cell + 1px border left
width: th.width() + 10 // 10 is summ of padding-left and right of each cell
});
});
它实际上使用了桌子后面的div，然后在每次TH点击时，它根据TH大小和左偏移位置调整高亮度DIV的宽度和左CSS属性。
我还使用jQuery使其更易于阅读和理解，如果您需要原生JavaScript请告诉我
希望它有所帮助。
