Descrizione

Sample showing a grid with a large dataset: http://plnkr.co/edit/VCjtmkSjEMC59BFGmyT7?p=preview

Click the button at the top to cycle the grid columns being set to include only two, three then four fields. I notice around a 300ms delay until the grid redraws to show the changed headers. This makes the interface feel laggy. Scrolling through the dataset once the headers have updated is smooth however.

On a smaller dataset (comment out the "data = data.concat(data);" line), the rendering delay isn't as noticeable.

Are there any workarounds for this?

Thanks for the great library!
