Set column styling

Hi, is there a way to add styling elements to an individual column (left border).

I found a way to change the color, and add styling to header elements through setHeader, attachHeader but not for a column.

Thank you!

Unfortunately such feature is not available.
You may only set the style for the individual cells in your grid.
