Pinned Column Vertical Line?

I noticed for the ag-grid, there’s a vertical line to split pinned vs unpinned columns.

Currently right now, the NG Grid has a line splitting the header but not between the rows themselves. Is there any way of enabling that?

EDIT:

After setting up a row hover for the grid, that atleast segments between pinned and unpinned columns. If the split can’t be done, than this atleast helps as a work around.
