How to get row index in angular ui-grid 3.0

There isn't a way to get the index of the row easily, so it depends what you're trying to do. What do you expect the numbering to do when someone sorts the data - do you want the numbers to stay as they were in the original data, or do you want them to change and align to the new sort order?

In the FAQ http://ui-grid.info/docs/#/tutorial/499_FAQ we find:

The question here is what you're really trying to achieve. Do you want the actual row index, or that you want to display a sequential id in all your rows?

If the latter, then you can do it by just adding a counter column to your data:

$scope.myData.forEach( function( row, index){
  row.sequence = index;
});

If you want to show the index of the row within the grid internals, then it depends on which internal you want. You can get the index of the row within grid.rows, which would show the row as it stands in the original rows list (not filtered nor sorted), or the index of the row within grid.renderContainers.body.visibleRowCache (filtered and sorted), or the render index of the row within the currently displayed rows (given virtualisation, this is generally a particularly useless number).

If you're OK that whenever someone sorts or filters then the numbers will change, then you could do it with a cellTemplate, which would be something like:

cellTemplate: '<div class="ui-grid-cell-contents">{{grid.renderContainers.body.visibleRowCache.indexOf(row)}}</div>'

cellTemplate: ' {{rowRenderIndex + 1}}'
