显示列使用div动态第一列固定，其余部分使用水平滚动条

问题描述 投票：1回答：2

我需要你的帮助。

我正在创建一个带有动态列的N级嵌套表

所以我想要做的是，我想根据用户选择创建一个具有可变列数的表，因为我创建了一个简单的下拉框，根据下拉选择，这些选定的列将出现在表

我想要的是我的第一列表应该始终是固定的，而其他列可以水平滚动，这些列的宽度应该调整为列显示或隐藏

我不想使用任何外部库。我已经基于div和网格CSS创建了一个自定义表

以下是我到目前为止所做的事情的截图

enter image description here

这是代码供参考：

HTML：

<ng-container *ngFor="let rData of reportData; let i = index; last as isLast" >
  <div class="myTr report-row">
    <div class="myTd">
        <button 
           class="btn report-btn-sm" 
           *ngIf="checkIfHaveMoreSplits(this.splitOpt[0].id) !== 0 && rData.isCollapsed == true"
           (click)="splitData(rowWiseFilterObj(rData,this.splitOpt[0].id),this.splitOpt[0].id,sFilters,splitOpt,i,rData,selectedDate)"
           row="rData">+</button>
        <button 
           class="btn report-btn-sm" 
           *ngIf="checkIfHaveMoreSplits(this.splitOpt[0].id) !== 0 && rData.isCollapsed == false" 
           (click)="removeDynamicComponent(rData,i)"
           >-</button>
           <span *ngIf="this.splitOpt[0].id == 'campid'">{{rData['campaign_name']}}</span>

          <span *ngIf="this.splitOpt[0].id !== '__time' && this.splitOpt[0].id !== 'campid'">{{rData[this.splitOpt[0].id]}}</span>
          <span *ngIf="this.splitOpt[0].id === '__time'">{{ rData[this.splitOpt[0].id]  | date:'dd-MM-yyyy HH:mm:ss Z'}}</span>

您可以使用带有flex布局的<div>s重新制作表格。

我在下面写一个完整的例子。你没有表的所有灵活性，但它非常强大。您还可以将列滚动条固定到页面，并使其始终可见，即使表格大于页面高度也是如此。和更多...

你会看到，我使可滚动列的宽度相同。您可以设置不同的宽度。我会使用列的类来做到这一点。

我相信代码很容易理解。如果您需要帮助，或者想要使用更多Flex布局的强大功能，可以看到以下页面：https://css-tricks.com/snippets/css/a-guide-to-flexbox/

让所有人一起移动的javascript是最简单的事情。想法是获取滚动事件并使用overflow: hidden应用相同的滚动线。

要创建新列，就像在<table>上创建它一样简单，只需将<div>s放入.myTdGroup元素中。

<style>
  .myTable {
    font-family: sans-serif;
    font-size: 15px;
    width: 450px;
    border: 2px solid #BBB;
    position: relative;
  }
  .myTr {
    display: flex;
    align-items: center;
  }
  .myTr:nth-child(odd) { background: #DDD }
  .myTdGroupBox {
    overflow: hidden;
  }
  .myTdGroup {
    display: flex;
    align-items: center;
    width: 500px;
  }
  .myTr:last-child { background: #777 }
  .myTr:last-child .myTdGroupBox { overflow-x: scroll }
  .myTr:last-child .myTd { padding: .1px 0 0 0 }
  .myTd {
    margin: 0 1em;
    padding: .5em 0;
    flex-grow: 1;
    flex-basis: 50px;
    overflow-x: auto;
    white-space: nowrap;
  }
  .myTr > .myTd { flex-basis: 150px; }
</style>

<div class="myTable">
  <div class="myTr">
    <div class="myTd">Line A</div>
    <div class="myTdGroupBox"><div class="myTdGroup">
      <div class="myTd">A1</div>
      <div class="myTd">A222</div>
      <div class="myTd">A333</div>
      <div class="myTd">A444</div>
      <div class="myTd">A555</div>
      <div class="myTd">A666</div>
    </div></div>
  </div>
  <div class="myTr">
    <div class="myTd">Line BBBBB</div>
    <div class="myTdGroupBox"><div class="myTdGroup">

      <div class="myTd">C222</div>
      <div class="myTd">C3</div>
      <div class="myTd">C 444 444 444 end</div>
      <div class="myTd">C555</div>
      <div class="myTd">C666</div>
    </div></div>
  </div>
  <div class="myTr">
    <div class="myTd">Line DDD</div>
    <div class="myTdGroupBox"><div class="myTdGroup">
      <div class="myTd">D111</div>

    <div class="myTdGroupBox"><div class="myTdGroup">
      <div class="myTd"></div>
    </div></div>
  </div>
</div>

<script>
var contentGroups = document.querySelectorAll('.myTr:not(:last-child) .myTdGroupBox');
var ctrlGroup = document.querySelector('.myTr:last-child .myTdGroupBox');
ctrlGroup.addEventListener('scroll', (ev)=> {
    contentGroups.forEach((g)=> g.scrollTo(ctrlGroup.scrollLeft, 0) );
});
</script>

Janak Prajapati，早些时候我做了类似于固定桌子的事情。
