I hide the second table (in the secont column) until an item has been selected in the first table .
Unfortunately as this snippet shows http://webix.com/snippet/9b6df4fd
it does not work as expected.
It seems that autowidth : true, in the first table is what causes problems
We will fix this behavior in the next build, for now just change code like next
$$('y2').show();
$$('y2').resize();
it will fix the issue for now.
great! glad it was not false alarm.
