Showing and Hiding Columns and data Conditionally

[Charlston]

I am converting a MVC table grid to a Telerik Grid. While looking at it, there are conditional columns. For example: 

 

@if (Model?.GroupDetail?.IsMec == false)
                                    {
                                        <th class="text-secondary" style="width: 140px;">Group Info</th>
                                    }

<th class="text-secondary">
                                        @if (Model?.GroupDetail?.IsMec == false)
                                        {
                                            <text>Office</text>
                                        }
                                        else
                                        {
                                            <text>Role</text>
                                        }
                                    </th>

How would I go about recreating something like this for the grid
