【中文标题】隐藏列时如何保留表格列的宽度?【英文标题】:How to retain the width of table columns when hiding columns? 【发布时间】:2019-03-12 05:20:31 【问题描述】:我有一个包含六列的表,其中五列可以根据用户选择隐藏。我遇到的问题是,当隐藏列时,所有其他列都会扩展以填充隐藏列占用的空间。相反,我希望该列隐藏,其余列向左移动,同时保留给定的宽度。我在这里找到的答案似乎都没有解决这个特定问题。
下面是我的 js 和 css 的截图以及屏幕截图。
js:
<table className="hours table table-bordered table-sm" table-layout="fixed">
<thead>
<tr>
<th scope="col"
colSpan="3"
className="row-dow"
>
Hours
</th>
<th
scope="col"
colSpan="2"
align="center"
hidden=this.state.kitchenHoursSame
className="row-16"
>
Kitchen Hours
</th>
<th
scope="col"
colSpan="2"
align="center"
hidden=!this.state.breakfast
className="row-16"
>
Breakfast Special
</th>
...
</tr>
<tr>
<th
scope="col"
// className="row-8 "
>
Day
</th>
<th
scope="col"
className="row-8"
>
Open
</th>
<th
scope="col"
className="row-8"
>
Close
</th>
<th
scope="col"
hidden=this.state.kitchenHoursSame
className="row-8"
>
Open
</th>
<th
scope="col"
hidden=this.state.kitchenHoursSame
className="row-8"
>
Close
</th>
<th
scope="col"
hidden=!this.state.breakfast
className="row-8"
>
1234567890123
</th>
<th
scope="col"
hidden=!this.state.breakfast
className="row-8"
>
End
</th>
...
</tr>
</thead>
<tbody>
this.state.DOW.map((dowList, i) =>
<tr>
<th scope="row" key=dowList.i>dowList.long</th>
<td>
<select name="timeofday"
value=this.state.timeofday
onChange=this.handleInputChange>
<option>
(open)
</option>
</select>
</td>
...
</tr>
)
</tbody>
</table>
css:
.hours
table-layout: fixed;
/* width: 90%; */
width: 1500px;
white-space: nowrap;
.hours td
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
.row-dow
width: 20px;
.row-16
width: 16px;
.row-8
width: 8px;
即使有人告诉我不应该使用表格而应该使用其他东西,任何帮助都将不胜感激。
【问题讨论】:
表格宽度是 100% 吗? 没有。当前为 1500 像素。 .hours 表格布局:固定; /* 宽度:90%; */ 宽度:1500px;空白:nowrap; @IvanBurnaev 说如果你给表格一个宽度,当列被删除时它会保留宽度。 您的表格应该有一个auto
宽度,以便在删除列时缩小。否则,如果表格保持它的大小,内部列将包含所有位置并且宽度会增加。
【参考方案1】:
下面的 sn-p 向您展示了在删除列时不同宽度定义的表格的行为。
window.addEventListener("load", () =>
const firstTDs = Array.from(
document.querySelectorAll("td:nth-child(3)")
).concat(Array.from(document.querySelectorAll("th:nth-child(3)")));
document.querySelector(".remove").addEventListener(
"click",
() =>
firstTDs.forEach(td =>
td.parentNode.removeChild(td);
);
,
once: true
);
);
.full-width
width: 100%;
.fixed-width
width: 600px;

【参考方案2】:如果你每次渲染表格内容都没有问题,这可以使用css属性visibility: hidden;
来处理,它隐藏了dom中占用空间的元素。 查看:visibilty hidden
方法:
我没有在th
或td
上使用hidden
属性,而是使用了class = hideColumn
,它被定义为隐藏元素。
接下来border: none
移除元素的边框。
在你的情况下,你也可以使用 'class' 属性来实现这一点。
如果这没有帮助,请在 cmets 中告诉我,或者是否可以采取任何措施来接近所需的解决方案。

.otherDiv .hideColumn

.otherDiv td, th
border-top: 1px solid #dddddd;
border-bottom: 1px solid #dddddd;
text-align: left;
padding: 8px;
<div class='otherDiv'>
<h2>Visible All Column Table</h2>
