隐藏列时如何保留表列的宽度？

标签： css reactjs html-table css-tables

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，当隐藏某个列时，所有其他列都会扩展以填充该隐藏列所占据的空间。我想发生的是使该列仅隐藏，其余的列向左移动，同时保留给定的宽度。我在这里找不到的答案似乎都不能解决这个特定问题。

下面是我的js和css以及屏幕抓取的片段。

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;
}

All columns selected

Kitchen column hidden

即使被告知我不应该使用表，而应该使用其他东西，也可以提供任何帮助。

如果每次在呈现表内容时都没有问题，可以使用css属性visibility: hidden;来处理，该属性将隐藏dom中占用空间的元素。
请参见：visibilty hidden

方法：

  • 我使用hidden来隐藏元素，而不是在th或td上使用class = hideColumn属性。

  • 下一步border: none，以从元素中删除边框。

      

    根据您的情况，您还可以使用'class'属性来实现此目的。

    如果这没有帮助，请在评论中让我知道，
    或者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>

<h2>Hidden 2nd Column Table</h2>

方法2：

  • 只需使文本透明即可。

.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'>

下面的代码片段向您展示了当要删除列时不同宽度定义的表的行为。

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;
}
