Cell Merging (Angular)

The FlexGrid control supports content-driven cell merging. To enable cell merging, set the allowMerging property to indicate what part or parts of the grid you want to merge, and set the allowMerging property on specific rows and columns to true. Once you do that, the grid will merges cells that have the same content, grouping the data visually.
