SmartAdmin DataTables -如何从component.ts导入ajax数据

Question

我正在使用SmartAdmin角5模板来呈现一个DataTable。我已经修改为LoginHistory的JSON datatable示例从存储在web应用程序中的JSON文件中获取ajax数据，如下所示。这个很好用。但是，如何修改它以从component.ts中定义的字符串中获取数据呢？

loginhistory.component.html

<div id="content">

  <div class="row">
    <sa-big-breadcrumbs [items]="['Table', 'Data Tables']" icon="table"
                        class="col-xs-12 col-sm-7 col-md-7 col-lg-4"></sa-big-breadcrumbs>
  </div>

  <sa-widgets-grid>
    <div class="row">
      <article class="col-sm-12">
        <div sa-widget [editbutton]="false" color="blueDark">
          <header>
            <span class="widget-icon"> <i class="fa fa-table"></i> </span>
            <h2>Export to PDF / Excel</h2>
          </header>
          <div>
            <div class="widget-body no-padding">

              <sa-datatable
                [options]="{
                  ajax: '../../assets/api/tables/datatables.standard.json', // <<<<<<< HOW TO USE loginHistoryData FROM loginhistory.component.ts????
                  columns: [
                  {data: 'id'},
                  {data: 'name'},
                  {data: 'phone'},
                  {data: 'company'},

                  ],
                  buttons: [
                    'copy', 'excel', 'pdf', 'print'

          + '}';
  }
}

一个小小的尝试和错误解决了这个问题。只需将ajax标签更改为data，并包含component.ts参数的名称。

我还使用类型记录命名来清除loginHistoryData参数，而不是使用字符串。

loginhistory.component.html

<div id="content">

  <div class="row">
    <sa-big-breadcrumbs [items]="['Table', 'Data Tables']" icon="table"
                        class="col-xs-12 col-sm-7 col-md-7 col-lg-4"></sa-big-breadcrumbs>
  </div>

  <sa-widgets-grid>
    <div class="row">
      <article class="col-sm-12">
        <div sa-widget [editbutton]="false" color="blueDark">
          <header>
            <span class="widget-icon"> <i class="fa fa-table"></i> </span>
            <h2>Export to PDF / Excel</h2>
          </header>
          <div>
            <div class="widget-body no-padding">

              <sa-datatable
                [options]="{
                  data: loginHistoryData, //<<<< change ajax to data and add the name of the component.ts parameter
                  columns: [
                  {data: 'id'},
                  {data: 'name'},

                  {data: 'city'},
                  {data: 'date'}
                  ],
                  buttons: [
