I need to show multiple values (rank and vote) together separated by space as key:value in a webix datatable cell from the following structure :

id2: [{"rank":2, "vote":50}, {"rank":3, "vote":10}]

I want to show only the first element of this above array.

My snippet is here : <https://webix.com/snippet/ca50874d>

I am not able to figure out how to show these two values together in one cell.
Please help.

Thanks.
