I have seen this question and the solution was pretty straightforward, however this plunker doesn't seem to work with Angular 1.33 which I use in my project.
Here is the same plunker with the issue (only updated Angular to version 1.33) .
Html
<table ng-table="tableParams" show-filter="true" class="table">
<tr class='listing' ng-repeat="invoice in $data">
<td data-title="'Invoice No.'" sortable="'no'" filter="{'no':'text'}">
{{invoice.no}}
</td>
<td data-title="'Date'" sortable="'date'" filter="{'date':'text'}">
{{invoice.date}}
</td>
<td data-title="'Client'" sortable="'client.fullname'" filter="{'client.fullname':'text'}">
{{invoice.client.fullname}}
</td>
</tr>
