rendering.columns.strictWidths

Whether all columns should use one fixed width, resolved from columnDefaults.width or a fallback width. When enabled, the grid skips per-column width and offset calculations, column resizing mode initialization and column resize handles.

Enabling this option can improve initialization performance for very wide grids, especially together with column virtualization.
