Html 如何在angular中使用css创建类似div的引导弹出窗口

我有一个表，它的数据来自循环，这里有一个“点击这里”链接，当你点击链接时，一个div将打开position-absolute，这个div我想用css创建一个bootstrap模式。如果它是好的引导它ok。当你按下关闭按钮时，弹出窗口应该像引导一样关闭。下面是代码

app.component.html 可在以下设备上测试代码：

从W3Schools获得了一些代码，还添加了2个接受索引的javascript函数。代码是自解释的

app.component.html

<table class="table border">
    <thead>
    <tr>
      <ng-container *ngFor="let column of columns; let i = index">
        <th>{{ column }}</th>
      </ng-container>
    </tr>
    </thead>
    <tbody>
        <tr *ngFor="let row of groups;let i = index">
            <td>{{row.name}}</td>
            <td>{{row.items}}</td>
            <td>{{row.Status.length}}-<span (click)="displayBox(i)" style="border:1px solid;" >Click here</span>
               <div  class="modal" id="model_{{i}}" style="display:none;">
                  <div class="modal-content"> 
                    <span (click)="closeBox(i)" class="close">&times;</span>
                  <span *ngFor="let item of row.Status;let j = index">
                    {{item.name}}
                    <span *ngIf="j != row.Status.length - 1">,</span>
                  </span>
                </div>
                </div>
           </td>
            <td>
                <span *ngFor="let item of row.loc;let k = index">
                   {{item.name}}
                   <span *ngIf="k != row.loc.length - 1">,</span>
                </span>     
           </td>
        </tr>
