AngularJS Question

Angular ng-table dynamic headers doesn't work inside

I am using ng-table with dynamic columns, using the creator's example found at http://bazalt-cms.com/ng-table/example/20

It worked just fine, until i tried to wrap on a directive with transclude, witch caused the headers to disappear as seen on http://plnkr.co/edit/mjYVEf.

Has anybody came across the same issue?

Answer

Define a template for a header, and set a template-header attribute of ng-table.

You can see the code http://plnkr.co/edit/EXVkjabwfjCreNZAY1c2?p=preview

Define template header

<script id="sample_ng_header" type="text/ng-template">
  <tr>
      <th ng-repeat="column in columns" ng-show="column.visible"
          class="text-center sortable" ng-class="{
              'sort-asc': tableParams.isSortBy(column.field, 'asc'),
              'sort-desc': tableParams.isSortBy(column.field, 'desc')
            }"
          ng-click="tableParams.sorting(column.field, tableParams.isSortBy(column.field, 'asc') ? 'desc' : 'asc')">
          {{column.title}}
      </th>
      <!--<th>Columns:{{columns.length}}</th>-->
  </tr>
</script>

Set template-header attribute of ng-table with your template

<table ng-table="tableParams" template-header="sample_ng_header" show-filter="true" class="table">
  <tbody>
  <tr ng-repeat="user in $data">
      <td ng-repeat="column in columns" ng-show="column.visible" sortable="column.field">
          {{user[column.field]}}
      </td>
  </tr>
  </tbody>
</table>
