隐藏列时如何保持table列的宽度？

Question

我有一个有六列的 table，其中五列可以根据用户选择隐藏。我遇到的问题是，当一个列被隐藏时，所有其他列都会扩展以填充隐藏列占用的 space 。相反，我想要发生的是该列仅隐藏，其余列向左移动，同时保留给定的宽度。 None 我在这里找到的答案似乎解决了这个特定问题。

下面是我的 js 和 css 的片段以及屏幕截图。

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 tables 而应该使用其他东西，我们也将不胜感激。

Answer 1

如果你每次渲染 table 内容都没有问题，这可以使用 css 属性 visibility: hidden; 来处理，它隐藏了 space 占用的元素在 dom。
寻找：visibilty hidden

方法：

我没有在 th 或 td 上使用 hidden 属性，而是使用了定义为隐藏元素的 class = hideColumn。
下一步 border: none 删除元素的边框。

In your case, you can also use 'class' attribute to achieve this.

如果这没有帮助，请在评论中告诉我，
或者是否可以采取任何措施使它接近所需的解决方案。

table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
    font-size: 10px;
}

.hideColumn {
    visibility: hidden;
    border: none;
}

h2 { 
    font-size: 12px;
}

td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
}

<h2>Visible All Column Table</h2>

<table>
  <tr>
    <th >Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td >Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>
<br>
<h2>Hidden 1st Column Table</h2>

<table>
  <tr>
    <th class='hideColumn'>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td class='hideColumn'>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td class='hideColumn'>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>
<br>
<h2>Hidden 2nd Column Table</h2>

<table>
  <tr>
    <th >Company</th>
    <th class='hideColumn'>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td >Alfreds Futterkiste</td>
    <td class='hideColumn'>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td >Centro comercial Moctezuma</td>
    <td class='hideColumn'>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>

方法二：

将文本设为透明即可。

.otherDiv table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
    font-size: 10px;
    border: 1px solid #dddddd;
}

.otherDiv .hideColumn {
    color: transparent;
}

h2 { 
    font-size: 12px;
}

.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>

<table>
  <tr>
    <th >Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td >Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>
<br>
<h2>Hidden 1st Column Table</h2>

<table>
  <tr>
    <th class='hideColumn'>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td class='hideColumn'>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td class='hideColumn'>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>
<br>
<h2>Hidden 2nd Column Table</h2>

<table>
  <tr>
    <th >Company</th>
    <th class='hideColumn'>Contact</th>
    <th>Country</th>
  </tr>
  <tr >
    <td >Alfreds Futterkiste</td>
    <td class='hideColumn'>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td >Centro comercial Moctezuma</td>
    <td class='hideColumn'>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
</table>

</div>

Answer 2

下面的代码片段向您展示了不同宽度定义的表格在删除列时的行为方式。

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;
}
