css - 隐藏列时如何保持表格列的宽度？

Question

我有一个包含六列的表格，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空间。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。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;
}

即使被告知我不应该使用表格而应该使用其他东西，我们也将不胜感激。

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。

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;
}
