Grid Column Resizing
Use the Grid Column Resizing to indicate that the columns of the Grid are resizable and allow the user to grab their header's right border as a handle to adjust their width. The Grid Column Resizing is visually identical to the Ignite UI for Angular Grid Column Resizing Feature
Grid Column Resizing Demo

Header Cell
The Grid Column Resizing as a header cell feature has been deprecated in Figma and if you are using AppBuilder to generate your design, you should apply it directly there after the code generation.
Column Resizing Indicator Feature
The Grid has a Column Resizing Indicator
component in the Base Components
that represents a highlight border of the whole column where resizing occurs. Adding this component has only a visual effect on your design to make it look more realistic.
