由於官網無法登陸所以參考csdn angular拖拽案例 滾動條屬性設定

需求：把ng-zorro表格頭部做成可拖拽的形式

思路：拖拽表格最簡單的實現就是把表格的元素設計成陣列渲染，通過改變陣列元素來渲染表頭，上程式碼

APP.component.html

  <nz-table #basicTable [nzData]="listOfData" [nzPageSize]="2" [nzPageSizeOptions]="[1,2,3,4,5]"
    [nzShowPagination]="true" nzShowSizeChanger [nzScroll]="{y:'100px'}"
 
>
    <thead>
      <tr cdkDropListOrientation="horizontal"  class="example-list"  cdkDropList (cdkDropListDropped)="droptest($event)">
        <th *ngFor="let i of tharr;" class="example-box"  nzAlign="center" cdkDrag>{{i}} 
        </th>
      </tr>
    </thead>
    <tbody>
      <tr *ngFor="
 
let data of basicTable.data">
        <td *ngFor="let i of tharr let index=index" [nzAlign]="thFont(index)">{{ thHear(data,i) }} </td>
      </tr>
    </tbody>
  </nz-table>
