Grid Column Pinning
Use the Grid Column Pinning as a mechanism to fix the first few columns of a scrollable Grid to the left. Now, when the user scrolls, all other columns move left and right except for the pinned ones. The pinned columns always appear on top of the scrollable ones. The Grid Column Pinning is visually identical to the Ignite UI for Angular Grid Column Pinning Feature

Header Cell Feature
The Grid Column Pinning 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.
The Built-In Column Pinning can be used through the Grid's toolbar which by default contains a button (combined with a combo dropdown) that lets you configure the pin state of the columns for the whole grid.

Custom Column Pinning
It is also possible to add a custom pinning action in the Grid Header Cell. In Figma you need to go to the Header Cell layer, select either the Feature Left
or Feature Right
and change its Type
property from None
to Icon Template
. Of course, you would probably also want to rearrange the column order so that the pinned ones come first when looking left to right.
Cell Right Border
The right-most pinned column should have its Right Border
set to Pinned
both for the Header and all Body Cells of the column. This is shown on the image below for all cells of the second column since "Status" is pinned.
