html - Using an index with ng-table over multiple pages -

-

i using ng-table display below data.

i want first column index number persists on pages (eg page rows 100-199 should have index 100-199).

currently index resets , starts @ 0 every page. have tried 

{{ (farmparams.page() * farmparams.count()) + index }}

but first page start @ index 100 in case.

<table ng-table="vm.farmparams" class="table table-hover"> <tr ng-repeat="row in $data">     <td data-title="''" filter="{index : 'text'}" sortable="'index'">{{$index}}</td>     <td data-title="'planted:'" filter="{planted : 'text'}" sortable="'planted'">{{row.planted}}</td>     <td data-title="'harvested'" filter="{harvested: 'text'}" sortable="'harvested'">{{row.harvested}} </td> </tr> </table>

seems subtract 1 page then.

{{ ((farmparams.page() - 1) * farmparams.count()) + index }}
