Grids and Grid Cells are just Containers with a bit of pre-scripted overlay.

You could easily build a customized component to do what you would like.

so u mean that using kontx.control.grid we cannot give the spacing between cells but have to build our own one

I do not believe so... Any not in any settings we have seen.

You can set a "padding" value that will adjust the border spacing, but nothing to adjust the gap between cells.
