背景：Extjs使用久了就不想多写html了，最近使用angular4.2.4+ng-bootstrap1.0.0-alpha.25+bootstrap4.0.0-alpha.6+scss开发应用需要写html，封装成grid组件，通过ts设置即可加载显示数据，暂时未实现完，记录

效果：

1.grid.component.html

  <div class="col-md-12">
    <table [class]="'table table-bordered table-hover '+gconfig.cls" >
      <thead>
      <tr >
        <th *ngFor="let column of columns;let i = index"  [class]="'text-center ' + column.widthCls">{{column.header}}</th>
      </tr>
      </thead>
      <tbody>
      <tr *ngFor="let data of records;let i = index" [class]="data.checked?'table-success':''"  (click)="rowClick(data)">
          <td *ngFor="let column of columns;let j = index" class="text-center">
            {{data[column.dataIndex]}}
          </td>
      </tr>
      </tbody>
    </table>

    <c-pagination [hidden]="!gconfig.ispage" [total]="pageConfig.total" [pageList]="pageConfig.pageList" [btnCls]="'btn-outline-info'" (onPageChanged)="onDataChanged($event)"></c-pagination>
  </div>
