I'm not sure if this is a bug but if you leave the size off of a column, it stretches to fill the remaining area. However I discovered that this does NOT happen if you lock one of your columns. If you do this, the column doesn't render at all.
Hello John,
This is not a bug, but a requirement when using locked columns, see: https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/grid/columns/locked
"Set explicit pixel widths to all columns to allow the Grid to adjust the layout of the frozen and non-frozen table parts."
