The freezing feature enables the user to freeze certain rows/columns to scroll remaining movable content. This can be achieved by setting frozenRows and frozenColumns property. In this demo sample, the first column and two rows are set to frozen by using the frozenRows and frozenColumns properties. Injecting Module: Grid component features are segregated into individual feature-wise modules. To use frozen rows and columns feature, we need to inject FreezeService into the @NgModule.providers section.
